Thumbs up for ultrasonic record cleaning

Sorry slaw, you missed my apparently bad attempt at humor.  My question was how terry could evaluate a record if it was still sealed?  Obviously that was not his intent, but that's the way it read.

On subject, I still utilize a VPI machine, although I intended to set up a US cleaner.  I will say that I too have sometimes noted LPs which appear quite beat up but play cleanly, while I also have some which look "pristine" but do have pops or crackles.  I'm hoping the US will eliminate those.

@pryso ,

I think I really got the gist of your post. Your recognition of what I initially thought I perceived is refreshing to me.

So I stand by my my initial reaction.

"Obviously that was not his intent, but that's the way I read it".

Which is it?

I perceived it in the most remarkably unremarkable way.

IE: I think we're OK!

Well I am 12 records in and completely sold on US cleaning.  I did some old records and some new.  One was even sealed since 1988.  I played that one first and although 80s vinyl quality are infamously crappy, this pressing was fantastic.  Especially for 80s Thrash Metal.  But what sold me most was cleaning my early US-pressed Led Zep III.  It went from a VG to arguably a NM record.  And for this record, there are a lot of acoustic parts, so it was quite annoying with all the pops and ticks.  Now, it's fantastic.  I did a PF Animals early German pressing with similar results.  A '73 UK pressing of PF's Darkside of the Moon, same result.  Plays fantastic now.  The only disappointment was my RL Led Zep II pressing.  The thing is just mangled with scratches though :(  But it definitely sounds better than it did before.  I'm going to do another batch this afternoon.  This is fun!

Damned if I don't feel like Samson ...

I also just put a pump together.  Very similar to Slaw. 

I used a slightly stronger motor from the same company - A108, 5 Amp, 1.2 gpm.  But honestly, I think it's overkill.  That pump moves a lot of water, so I wouldn't obsess about the power of the pump motor.  A motor moving half the fluid seems like it would be plenty.  

Nothing elegant about my solution, just a 1 micron filter, pump, and power supply.  No housing.

I think Slaw's idea of using a plug to be able to connect and disconnect the power supply from the pump does seem convenient.  Having a quick connect from the tank to the pump might also be convenient.

More to tinker with, but the net is this setup seems to clean the fluid very quickly.
