  1. And why, he reckons, it's unwise to use (isopropyl) alcohol to clean vinyl records. Cheers, Owen Dark Lantern blog - http://darklanternforowen.wordpress.com/
  2. See @Juzbear's filtering set-up om page 47. Also @maxpina's in Italy, page 46. Cheers, Owen Dark Lantern blog - http://darklanternforowen.wordpress.com/
  3. They say stylus friction generates enough heat locally to 'plasticise' the vinyl - which is one reason why Kirmuss recommends pre-cleaning new records, in order to remove pressing residue & factory detritus, before first play. Regardless, the benefits of a good cleaning process are readily audible to anyone who wishes to try for themselves. Cheers, Owen Dark Lantern blog - http://darklanternforowen.wordpress.com/
  4. Chaps - my experience is that ultrasonic cleaning with a 0.1+% dilution pure, non-ionic, detergent-surfactant mix at ambient temp. gives excellent sonic results - more balanced tonally (without the slight brightness) than traditional (20%) iso-alcohol-water-surfactant cleaning & the stylus seems to track better (dynamics are more open at both ends of the freq band) - I suspect that detergent residue may be a factor, not unlike when using Lyra's SPT stylus treatment. Depending on season, anything from 18-35deg C works very well. I clean also new vinyl, to remove stamper-release residue before playing. This gives consistently good sonic improvements.

  5. Although some users report improved results with heating the fluid, I don't think that there is any need to turn on heating in these US cleaner tanks, the system cleans beautifully without heating, using just the 0.1 -0,5% surfactant/detergent mix. The ultrasonic action tends to raise the fluid temperature a little anyway (depending on how many records/cycles you run in a session). I do recommend vacuum-drying if you still have a record vacuum or such. And either filter of otherwise keep your fluid as refreshed as clean as possible.

  6. Someone brought to our attention this ebay.au link for the Ultrasonic Cleaner tank which appears to be the same as what we use & fits our kit: Price seems good at AU $166.99 for the '6.5L' model. (Model PS-30A) https://www.ebay.com.au/itm/Digital-Ultrasonic-Cleaner-Stainless-Steel-Heater-Timer-Industrial-Grade-1-3-30L/282539569913?hash=item41c8abb2f9:m:mZod3FFNC6C2NgX0NKn8Ixw&frcectupt=true Cheers, Owen Dark Lantern blog - http://darklanternforowen.wordpress.com/
  7. Hi @crtexcnndrm99 - excellent, we can have one packed for you within a day or so. When it's packed ready to ship, we'll Paypal you. Please PMessage me your postal name & address & email for Paypal. Cheers, Owen Dark Lantern blog - http://darklanternforowen.wordpress.com/
  8. Hi @crtexcnndrm99 Ultrasonic freq 'cavitation' penetrates deep into fine, deep recesses of objects, like record grooves, dislodging gunk - that brush-scrubbing does not manage to get to. If wish to add some detergent-surfactant to the water, it helps to 'solubilise' oily or adhered substances like record-pressing release-residues. This helps rapid air-drying of records, as the water 'films' thinly over the record surface. Or, ideally, use a record vacuum to vacuum-dry afterwards. Yes, 'kit' parts are here ready to ship - price is still A$149 + airmail $15. Assembly is simple, just 4 screws (+ 3 motor screws) - but we provide instructions & some cleaning advice. You just need to get the tank & rotisserie motor.... I was given this link recently to the PS-30A, 6.5L tank needed: https://www.ebay.com.au/itm/New-6-5L-Mechanical-Industrial-Ultrasonic-Cleaner-Ultra-Sonic-Wave-Tank-Basket/274098967977?hash=item3fd19255a9:g:LVsAAOSwEP5dnEwr&frcectupt=true https://www.bunnings.com.au/gasmate-240v-rotisserie-motor_p3180311 https://www.outdoorsdomain.com.au/gasmate-240v-rotisserie-motor/ https://www.ebay.com.au/p/1938162590 More info here - https://darklanternforowen.wordpress.com/2017/05/12/ultrasonic-record-cleaning-pt-2/ Cheers, Owen Dark Lantern blog - http://darklanternforowen.wordpress.com/
  9. I see that the 6.5L Ultrasonic tanks are available again: (The model no. should be PS-30A)) https://www.ebay.com.au/itm/New-6-5L-Mechanical-Industrial-Ultrasonic-Cleaner-Ultra-Sonic-Wave-Tank-Basket/274098967977?hash=item3fd19255a9:g:LVsAAOSwEP5dnEwr&frcectupt=true Cheers, Owen Dark Lantern blog - http://darklanternforowen.wordpress.com/
  10. Mark - I don't know the currents involved, but in amps (& preamps) I always go for big chunky bus wires, eg. 1mm or 1.6mm solid copper. You can model your PSU on PSUD if you want. for ripple & step load behaviour. Keeping ripple say 80dB (0.0001%) below last stage voltage.

  11. Ah OK - black masked PCB with white silkscreen, nice. Cheers, Owen Dark Lantern blog - http://darklanternforowen.wordpress.com/
  12. I've always admired nicely labelled chasses, but have only had it done one or two times for my DIY stuff. Did you have this chassis screen-printed or labelled professionally? Cheers, Owen Dark Lantern blog - http://darklanternforowen.wordpress.com/
  13. Chaps, If I may be so bold as to post a link here to our thread .... If interested... The kit is currently A$149 + airparcel postage $15 to most parts of AU. You just need to purchase a PS30A ultrasonic tank + a Gasmate rotisserie motor. Cheers, Owen Dark Lantern blog - http://darklanternforowen.wordpress.com/
  14. Chaps, an update: Just a note that current price of the kit is A$149 + airparcel postage $15 to most parts of AU. (Kit is as below.) You just need to purchase a model PS30A tank from ebay.au & a Gasmate rotisserie motor. Assembly involves 4 screws + attaching the motor with 3 screws. Cheers, Owen Dark Lantern blog - http://darklanternforowen.wordpress.com/
  15. A pic of one of our kits, from Mike in California. It's good to have a decent 1" (23-25mm) or so between records, for the ultrasonic cavitation to work nicely & in some cases if I'm really fussy, I'll clean only 2 records a time (with a double spacer between).
