ultrasound cleaning?

Anyone heard of the US-120A or US-60A ultra-sonic/sound(US) LP cleaners?

DiscUnion(Japan)
http://www.diskunion.co.jp/s_sale/goods/cleaner.html

Lists for Y80K($760), Y60K($570).

the asylum had a fair amt of discussion on the concept but none on commercial products. I have tried twice to get an acct on assylym but failed?

I live in Japan(from U.S.) where Nitty Gritty and VPIs cost 2X+ the U.S., refer to same discunion page.

I am just getting into vinyl so have few records but want to get started. I am going to have to import a VPI or Nitty Gritty which will add $100-$150 for shipping maybe 15% duty not to mention the admin effort(still cheaper than local purchase). I am considering cheapo manual gerry rigged route by manually washing and using vacuum with dedicated/custom brush.

I haven't heard of those before, and my Japanese is nonexistent. Any chance they have an English site?

John Chapman at BentAudio is working on an ultrasonic LP cleaner. He showed a prototype at VSAC but he hasn't released it yet.

I'm waiting like you...

John Chapman's design is interesting. You mount up to 7 LP's on a sort of rotisserie spit, kind of like baking a chicken. :) The motor rotates the records VERY SLOWLY through the bath. Only the bottom portion of the records is submerged, and the motor goes so slowly that the solution slides off the record and doesn't wet the label. John suggests a 5-10 minute cleaning cycle. No vacuum included, so if that proves necessary a second device will be needed.

What solution do you like best? How necessary is vaccuming.

Ogsarg and Mr. Kidknow,

MANY thanks for your input. As one who has been interested in the pending U/S RCM from BentAudio since it was first announced, I'm paying close attention. I'm going to point this thread out to John Chapman so he can consider the issues you've raised. (one hopes he has done so already).

If I got such a machine, I'd clean a junk LP repeatedly, increasing cleaning times and/or intensities to test for possible vinyl damage. IOW I'd *try* to wreck the LP, just to learn the limits for safe use.

As I mentioned, the design does keep the LP moving so that should help, according to Ogsarg. I believe it may also include a rinse tank.

Spinitch, if anything was left behind on the record it would just be some of the solution. If it's safe for vinyl it's hard to imagine it could damage a stylus. No exploding bubbles (imploding actually) once the U/S energy is turned off.
