Orpheus Silex Turntable


Recommended Posts

That’s the one. Came with a flip stylus that played 33 and 78. If I ever found another silex I would gladly pay what it’s worth. Sometimes you just get lucky.

Hello Orpheus Silex lovers. Picked up this gem at a garage sale for $20. Saw the familiar grace logo on the head shell and thought it must be worth that for the arm alone. After a relatively simple re

Also what's the size of the mounting screw if anyone knows 

The common  thread type used in the pre metric era was the British Association range. If the  outside diameter of the machine screw is approx. 4 mm as indicated by silex, then a BA No. 3 would be the nearest size to try.

All three legs are suspended under the 5 mm top. The leg support with the adjusting wheel has a washer and nut under the plinth to keep everything firm. It is all a pretty tight fit, especially around the motor. There are probably easier ways to go about it but I’d just inherited a table router so thought why not. I will check if I still have the templates. The bolts appear to be 4mm or whatever that is in imperial.hope this is of some help. I think there is a similar silex build on vinyl engine.

If you have some links about a plan for plinth or some links to build discussion would be great also

Just mounted mine on a temporary plinth. And first thing that's so obvious is the motor hum it's quite loud. I can also a bit of rattle from the iddler wheel. Most likely because of the humm/vibration or because the belt is not right anymore. Might need to do a full strip down but looking at some post the motor almost all has noise not sure if it will make a difference.

 

My last motor strip down of motor in similar era was the craftsman connoisseur. And the biggest improvement when I changed the motor running capacitors on the noise but doesn't look like the Silex any.

 

I can try just mounting an arm as it is and see how does it sound. What do you all think? Which path best spending time on first

I have an Orpheus Silex that I am wondering if I should sell as I am not using it at all.     However, my experience with the motor is that it ran very quietly. I know noise can be a relative thing, but I am surprised that people say it is noisy. I think the key thing is to get that motor platform hanging properly on good replacement rubbers.  Even the grommets I used worked well enough.   So, my take on it is to strip it and clean and lube then remount with proper rubber isolation.

Also does the spindle bearing uses oil or grease?

Light machine oil according to the manual. Someone on eBay lists copies of the manual occasionally and I think vinyl engine may even have a copy in the archives. I cannot find reference to the hollow spindle in some models but assume that is to allow oiling from above. I remove my platter to oil it but putting the belt on is a PITA. Your motor should be very quiet when overhauled, I revarnished mine and replaced the starting cap gave it a good polish and lube and it is almost entirely silent. Bad tyres on your idler or crappy o ring joint on your belt might make a noise.

Visco Static oil, see the manual and other info: https://www.vinylengine.com/library/orpheus/silex.shtml (free registration required)

 

Forget about the page with hand drawings suspending the silex on springs, that's someone's modification that I don't think is helpful.

Keep me in mind if you do. ?

I'm dying to get my hands on one so I can try to solve the isolation rubbers issue and make them available to other owners.

Sing out if such a solution is found!

I thought the isolation rubber issue has been resolved long time ago. All you need is sorbothane sheets cut out coin sized pieces and use a hole puncher for the screw.

 

Anyway looks like there is no starter or running caps on my motor. Anybody know should I put one if yes what's the size?

The capacitor* is fitted to  quieten noise from the turn on/off  switching process. It should be replaced with an X2 style metallised polypropylene capacitor and adding a 100 to 220 ohm series resistor will form a suppressor network. This combination should be fitted as close as possible to the switch and insulated with  heatshrink.    

                           

                       * Any value between 10nF to 100nF will do.

The spider (for the platter) suspension is not that critical
What is critical is the motor suspension rubbers
A fellow OS chap in Tas worked out a fabulous solution using the bulbs out of eye droppers
I obtained mine from an essential oil place
I have just finished my 3rd OS and they work a treat
It is the only solution that works perfectly

 I have not seen the underside of this  very early model Orpheus turntable with the fully cast baseplate, but I suspect it has the suspended  three legged spindle support bracket; however it does not allow the arm to be coupled directly to this bracket in the manner of the later Silex model.

Nice buy.  I love the 3rd party tonearm lift (can't recall the make).  I recommend discarding the DustBug ASAP!

 

The square turntable model was the first version, and was known as the Orpheus.

The Orpheus Silex was the latter version with the tonearm suspended from the mushroom support.

Hey t_mike, I gave it away to a friend today, I was hoping it would end up in the hands of someone who digs it. My friend is going to give it some TLC, but if he looses interest, I will get in touch here.

Thanks for your reply. I have no idea what it would be worth!

And another one slips by...   ?

 

Thanks for your consideration Sammi, I have my fingers crossed. Just don't let your friend butcher it, as it looks like a nice example.

Hi Mat-with-one-t.

I know it's a while since my original posting but I had a PC crash last year and once I got it up and running again I had no idea that I wasn't being informed of any postings. 

I have since found out a bit more about the OS turntable and that it is a bit of a rarity.

I was going to use the original arm and then thought I'd use a Grace arm that I have packed away but I would prefer to stay with an arm of the era and I recently purchase an Acos HGP39 (also known as the "black shadow") which is in great condition.

It's the speakers that got me interested. Your's are a copy of the original Wharfedale "Column 8" which used the model 8/145, 8" full range driver. the were installed in a black cloth sock to minimise the amount of dust settling on the driver. Unfortunately, when the drivers died or became faulty, people would just rip them out, throw the socks away and fit Super 8's which looked the same and most likely sounded pretty much the same. I have a genuine pair imported from the UK in the early 60's. I found them on a guy's veranda 2 years ago and they look like they were ready for the tip. He insisted on taking only $40.00 for them which I agreed to immediately and when I got them home, the drivers had been replaced with some cheap Pioneer drivers.

They have now been fully restored and have rebuilt Super 8's in them. They don't go very low but they do sound nice. By the way on the originals, the top section (approx. 4" high) is removable so that you can access the driver easily. Refer to the attached pics. You'll notice a similar one in the background. These were made in Brisbane in 1962 but I recently moved them on to pay for other projects.

Originals or not, if I were you, I would not be letting them go any time soon.

Cheers,

Andre

Interesting post about the Wharfedale's Andre.  They look similar to my father-in-law's Wharfedale's, which would has the original drivers in them, and still going.  From memory, they have a woofer facing downwards. I've tried looking for info to identify them without luck.  I will compare his to your photos when I next visit. 

 

He would have bought them with a Silex and a four-channel amp, which is also still going (at least 2 of the 4 are going, don't know about the others).  He has them set up in a very poor acoustic area so I can't get an idea of the quality of them, or how good the speakers are today, he listens to the football on them.  The Silex went years ago, he had a record-player turntable attached but the motor's siezed.

Hi all. I decided to give my Silex a new plinth, mainly to give a bit of protection around the new arm and also to fill in my time. At the moment I just have temporary spacers made up from layers of cork and hardwood ply. The result is surprisingly ok but I know there’s plenty of room for experiment and improvement. There’s plenty of opinion on the web but I don’t see anything definitive for my situation.  Should I be linking the layers for mass, isolating using Sorbothane, spikes or vibracones for feet, so many variables and many that are to expensive in this climate. Let me know what you think.

I like it

What are you using for the motor spider suspension 

I use eye dropper rubbers which work a treat, but more alternatives are always good. 

Thanks

Hi Colin. Yes the droppers are a good solution however during the rebuild I noticed they were starting to perish. At my workplace, a printing company, I spied a box of rubber suckers used on folding/finishing machinery. I fitted these face to face in pairs and seem to be perfect for the job. These are available from Birk and Blyme , clear blue Heidelberg bellows suckers. Half the fun for me with the Silex is the opportunity to experiment and tinker, hence my original post.  The original soft grommets on the motor are also on the way out. Speargun tube? Any suggestions. Thanks

I'm having rattling noise issue when the turntable is running. I think I narrow it down to the iddler wheel. I reckon the belt is not giving enough tensions that causes this rattle. Anyone have experienced the same?
