Hello Owen,

I'll try to run a batch without heating. I suspect that the microfiber cloth on the vac end is the culprit. I tried to look at one deposit making the pop with a very high magnifying glass (20x) and I saw nothing so it is smaller than something a 20x glass can show... And still give a big noise...

I was using a microfibre cloth from Bunnings, one of the cheaper ones you get in a pack of 6 or 8, to dry CDs after washing them. I found that if you held the CD at an angle to see the light reflected off it, you could just make out hundreds of tiny pieces of fibre. The cloths in question are the ones that have a cut pile sort of texture, similar to a shag pile carpet in miniature.

 

Even though it didn't seem to be a problem on the CDs, possibly because the pieces aren't big enough to obscure the pits, it could possibly affect playback of a LP.

Hi Andrew,   Re. vacuum dry vs. air dry ... and the (good) effect of using a 1-micron filter: this long weekend, I finally got my 1 micron filter working (with a 12v DC pump), with my

I use Wonder Cloths in the kitchen, they sound similar to your cut-pile bunnings cloths. When I use a new one it sheds tiny (micro I guess) fibres all over the place until it's used and rinsed a few times.

The micro fibre towel type cloths like the Meguiars Glass Cloth available at Supercheap/Autobarn/etc don't seem to have that fibre shedding issue.

George, I suggest a "microfibre cloth on the vac end " is not a good idea  Is this a vac machine you have put together?

 

My experience has been that you need to:

  • dry the LP using a 'wet/vac machine' like a Nitty Gritty to suck the gunk (in solution) out of the wet grooves
  • or use a filter loop (1 micron or less) off your us tank, so that there is no gunk in the solution at the bottom of the grooves.  Then you can air dry the LPs - or, better, blow dry them.

Hi,

The Us machine is running. Cold, one record at a time. I will soon run out of distilled water and can't buy the supplies for a filtration device. So experiment will stop soon. And it is fortunate, the missus is fed of hearing Tosca and Fidelio again and again. She is more into Punk Rock and Roll music right now 😉

Here is a picture of the suction device I put on my vacuum shop cleaner and the microcloth I used to protect the records. (a new one because I dumped the original after discovering the damage...)

I bet I did something wrong ....

Yes, this time, Miss Tosca is fixed good ! 4 time in the US, the last one cold and one disc at a time for around 15 minutes each record.

Now, I've to run the other record set I "cleaned" with the first method...

I can't find anywhere with the 6L utrasonic in stock under $200 or so at the moment, anyone else had any luck? 

Now that is interesting, been a while since I've even looked. That throws a spanner in the works.

You're welcome, there are plenty of sellers on Aliexpress selling exactly the same stuff with different brand names so search for PS-30A.

If I'm not mistaken, it seems a lot of companies share the same design and produce quite exactly the same stuff maybe designed by an official agency of some sort.

It appears so with an automotive timing lamp I bought 3 years ago. A friend of mine bought one without telling me and the function identically, are very very similar inside but different knobs and brand. Each part on one can go on the other ! Funny !

How does one attach a wall wart to a submersible pump, please? 12v DC and wallwart of suitable amperage.

 

s-l1600.jpg.eb2e858d50bdfa115d794b171581610a.jpg

 

I've asked silly questions before on SNA and will ask silly ones again in the future I'm sure. This is today's.

Hello,

Your pump should have a label stating the voltage (12V, obviously) and amperage it needs.

You have to buy a power supply apt to deliver 12V at the listed amperage or more (if the pump need 1A, try to find a 2A power supply to have some room).

Then, you have to plug one to the other.  I see that your pump has a red and a black wire.  The power supply you buy may have a plug at the end of the cable. If it has on the case, you'll find the wiring of the plug.

Now, up to you, either you find a mating plug and solder it to the pump or you cut the plug and solder the wires directly, put a connector of some sort, or anything that can isolate the wires properly and be sufficiently waterproof (the pump pumps water... so you will have water lying around, and even if 12V is not hazardous, a short may kill your power supply...)

Honestly, it is not rocket science. The power supply will have two wires of different colours. As you have the wiring on the case, you can tell which is the "+" and goes to the red one on the pump and which one is the "-" and goes to the black wire on the pump.

If you test the pump, install the plumbing first. Most often, these pumps die if run without water in them...

Hope this helps

Thank you. The 2 amps figure I wouldn't have got to myself, nor that the pump could die if switched on and nothing to pump. Appreciated. For me, Ohm's Law was so last millennium. 

 

I've been cautious ever since seeing a graph which showed that there's little room for error in voltage on wallwarts: when you need 12volt, then use 12 volt not 14 volt or 10 volt. [Rummages through 12v wall warts in box in garage: inventory of 6 at 0.5 to 1 amp, 3 at up to 1.5 amp, 1 at 2 amp and 1 at 2.5amp. The latter allows me to switch between various voltages from 5 to 14]. I'll use the 2 amp. Cheers.

My PS-30A UC just died on me.  Not much luck finding a replacement probably due to covid 19.  Can someone offer any advice as too where to purchase these. I have tried ebay and Aliexpress.  The shipping via Aliexpress is huge.

Hello,

I've bought some things from Aliexpress.

Yes, the delivery time can be awfully long but you are provided with a tracking number.

And if for any reason the package does not reach you, or the parcel is not fit for the job or as described you have Aliexpress insurance to reimburse you I used it a couple of time for item not showing. It was really quick.

As per your Australian unit, if it is like the one on aliexpress, it may come direct from China. You will support your country buying from them. Customs, taxes and people working there. it's your choice. Bear in mind that some shops are Aliexpress sellers proxy.

Hope this helps.

P.S. : mine come direct from China. And do a search on aliexpress for PS-30A ultrasonic cleaner and sort by terms like price and/or free shipping and see how it goes.

As you say quite costly. This one appears to be in stock for  $212.99 including post from Sydney. Not as cheap as they used to be but that is probably due to covid and supply issues.

I contacted the Seller and asked about the Warranty.

He says they will offer 2 years - but I'm skeptical about the return/replacement.

 

Having had two units both fail in the last year, I'm more skeptical than ever, unfortunately.  :(

Got my kit yesterday and put all the pieces together this morning.  Waiting on the reagents now so I can start cleaning. But I’m impatient. Has anyone used Finish or something readily available at Coles or bunnings for a surfactant?

Hi @Pipey - you can ultrasonic clean quite well with just plain water.

The surfactant adds some 'detergent' action esp. if your records are v dirty & speeds up air-drying by surface filming.

If you vacuum-dry, then the latter is un-important.

I think the surfactant/detergent cleaned vinyl tracks better afterwards too. 

 

I'd avoid unnecessary contaminants.

Hi @charlie_bird, a a quick summary....

Our DIY Ultrasonic Record Cleaner was inspired by ideas & work done by others on the 'net (see p.1).

A couple of us developed a prototype into a 'kit' (see P.2).

Many kits enabled us to place larger batch orders (SS laser-cuts & parts) & then offer attractively priced kits.

 

(Metal lasercutting is contracted out to an engineering shop, plastic moulding is done by my son, other parts are ordered in. Some machine work, cleaning up, pre-assembly & packing etc is largely done by me. We cover our costs + a bit for our time. We are spare-time enthusiasts, this is not an all-out business ;) )

 

IMG_1421.JPG.60aebe3451e8a819519c7acd4fab5582.JPG

 

EDIT: I forgot, current price of the 'kit' is A$149 + airmail postage $15 approx.

 

You will need to buy:

- Ultrasonic Cleaner Tank model PS-30A, 6L/6.5L size.

- 'Gasmate' BBQ Rotisserie motor (eg. from Bunnings, as below)

Was going to buy some of this to make a cleaning solution, and now it's sold out (in a suburb where everyone's panic buying water!)
I hope people know it's dangerous to drink de-mineralised water!

A USA enthusiast asked recently how easy is it to load & remove records from the tank, with our system..

 

I don't have a video but the images below I think show how the spindle is simply removed by hand (one hand), records loaded/unloaded & then re-inserted into the motor drive.

 

Oh, the spacers are semi-soft & do not damage the record labels.

Looks like the Ultrasonic baths have come down in price again from $213 to $160 including post.

But after putting a 10lt bath in my watch list I got an offer of 5% off and purchased one for AU $144.39 including post

From looking at other listings it appears to have 4 transducers instead of the 6lt baths 3 transducers.

10lt  will not work with the kit though

      Item Condition: Excellent Shipping Options: Pickup available but audition is not available.,Shipping is available at agreed cost. Suburb or Town: Hawthorn State: Victoria Payment Method: Paypal, EFT, Cash on Pickup etc Reason for selling: Looking to upgrade and automate the RCM process Further information:  I have had the Kirmuss since August 2018 (locally bought in Melbourne, 1st owner), probably have done around 400-500 records in this time.  I also bought a Record Doctor v5 at the time to vacuum dry the records that came off the Kirmuss wet.  I found this way worked very well and you could clean a batch of 30-50 records (dependent on water cleanliness) in a few hours  You can clean 2x12 Inch records on the Kirmuss move those to the Record Doctor for vacuum dry and then lay the records out on lint free cloth for up to 1 hour to dry before putting into clean inner sleeves.
       
      The RRP of a new Kirmuss (same model) is now $2800
      Most original items are included, including the cloth, mat, plastic drain pipe, camel hair brush, instructions, a couple of extra cleaning pads, power cord
      Used consumable items originally included:
      1) The included cleaning fluid is included but is 90% gone but it really is not required (used for extra pre-clean).  In the Kirmuss I used a combination of Distilled Water, Isopropyl Alchohol and Kodak Photo Flo 200
      2) Stylus cleaning liquid that i never used, but it is missing
      3) a record cleaning brush supplied is not included
       
      Record Doctor v5
      Selling both together as the Record Doctor is basically a giveaway to use in line with Kirmuss
      includes brush, use guide and a full bottle of record cleaner
      Note the 2nd last photo, shows the plastic liner on one section is loose from MDF in top left corner.  Some glue would stick that back down
       
      Kirmuss is the original double boxes and the Record Doctor comes in the original single box with foam support

      folks, considering an ultrasonic record cleaner... of the more affordable variety... I am not planning to spend on one costing the same as a turntable.
       
      And with more than my own share of home projects going on and plenty on the to do list no interest to be dong anything DIY in this regard.
       
      So what are folks experience with Affordable ultrasonic record cleaning machines of the non DIY variety ...
       
      theres this nobsound one on amazon - any thoughts or experience ? 
      nobsound on amazon
       
      dont want to get one and find a waste of cash ? last thing world needs is more land fill

      Item: Okki Nokki MKI  MKII RCM (White)
      Location: Blue Mountains, Sydney
      Price: $520
      Item Condition: Excellent
      Reason for selling: NLR
      Payment Method: Pickup - Cash, Paypal, COD Only
      Extra Info:
       
      EDIT: This is a MKII and not a MK1, as I first thought. This means it is manufactured in China (not Germany) and has a plastic instead of metal wand. Apologies for any confusion caused !
       
      For sale is a MK II Okki Nokki record cleaner, purchased in 2014 from Krispy Audio. Included in the sale are wands for 12” and 7” records, a clamp, and dust cover. The cover and 7” wand are additional purchases and retail for $115 and $75 respectively, and the 7" wand is unused. The dust cover is a must IMO, as keeping dust from a RCM is pretty important !
       
      The unit has seen mild to moderate use, and there are months where it’s barely used. 
       
      For anyone not familiar with the Okki Nokki, it is a wet - vacuum cleaning system, and works by first agitating debris from the record as it rotates via a brush placed along the grooves. After a few rotations (the unit has forward and reverse) the wand vacuums the liquid away, leaving you with a clean and hopefully crackle and pop - free record. It can’t perform miracles and fix a record retrieved from a dumpster, but for gunk, mould, fingerprints etc... it does a good job.  And with the debris and detritus new records come with, it’s a good idea to clean everything, not just 2nd hand purchases. Your needle will thank you. 
       
      A few months after I received the unit, it had an issue with the vacuum cleaner which was easily fixed by a fuse replacement and was a common problem with this model. It has been trouble - free ever since. 
       
      The original brush is long gone, so you’ll need to grab something suitable. There are plenty of options, and of course you’ll need to arm yourself with a record cleaning concoction. 
      I’ll also throw in a back - up set of spare velvet strips, which attach to the 12” wand and should be changed about every 50 records. 
       
      Shipping is possible as I have the box for the unit, however I don’t have one for the dust cover and so preference is given to local pick-up.

      Item: RCM Sensor 2 Phono stage + Kuzma Stabi-S Turntable (with PS2 speed controller) + Stogi-S Tonearm + Lyra Delos Cart
      Location: Mount Martha VIC, 3934
      Price:
      RCM SENSOR 2 = $3800  - SOLD (TT still available)
      KUZMA STABI-S TT + STOGI-S tonearm + PS2 Upgraded Power supply + LYRA DELOS MC Cartridge = $6750
      (comes with free perspex dust cover, as per photos)
      Package Deal: $10K (RRP for this setup is approx 15K. Please note I prefer to sell this whole package COMPLETE)
      Item Condition: 9.5/10
      Reason for selling: Have purchased a new car and need funds for that.
      Payment Method: Cash on Pickup or Bank Deposit. Paypal is my last preference and you will need to pay an extra 3%.
      Preference given to local pickup VIC buyers.
      I can send interstate at buyers expense, but very much prefer not to because of risk of damage.
      Extra Info: I bought these last year from Sonic Purity in May 2018, so this gear is approx 1 year old.
      The sale is somewhat regrettable, however I have other priorities now.
      The RCM Sensor 2 phono stage is magic and extracts every detail from the Cartridge while giving strong bass.
      (Has Furutech Connections, and external latest power supply)
      There are many reviews online about the phono stage and many who have heard it will confirm its high reputation.
      It has a multitude of loading and gain options.
      https://sonicpurity.com.au/store/phono-stages/rcm-sensor-2
      The Kuzma Turntable is equally amazing in sound and build quality.
      Latest 2018 30mm thick platter!
      https://sonicpurity.com.au/store/turntables/kuzma-stabi-s
      It has the upgraded power supply which means you don't need to change pulleys etc to change the speed.
      The speed controller has a digital display.
      It comes with Stogi-S tonearm, and LYRA DELOS cartridge. (has had little use, but is run in. I honestly don't know the hours)
      Those who know this cartridge can tell you that its super detailed in the high frequencies and still has gorgeous midrange and strong bass.
      Cartridge azimuth has been painstakingly set up by Rom at Sonic purity, using computer software.
      I look after my equipment with a lot of care and live in a smoke free / pet free home.
      Auditions are welcome at my home only for SERIOUS BUYERS.
      Upon sale I always make donations to SNA.
      Thanks for watching.
      Cheers,
      Paul.
      Happy Easter to all.
