:( :worthless: :)
I believe the worry about high temperatures is that the ultrasonic transducer itself generates heat and there can be tiny hot spots due to this - so the overall 40c temperature isn't the figure to worry about, so much as the potential for much higher temperatures in the bubbles down at groove level. Hence the Degritter switching off completely above 40c, and in the production version a cooling device to ensure even lower temperatures - to minimise the risk of very high temperatures where the cleaning beam is focused on the groove. With this in mind it's utter madness to clean records in a ultrasonic bath at 60c especially with IPA in the mix.
Having said that the Degritter uses a much higher frequency - 120kHz rather than 40 kHz - there's a lot more power being used and the emitters are directed at the record. Might not be such a need for such conservative measures with the bath method so long as overall temperatures are kept sensible.
Video done by another beta user, mine is a slightly later generation than this one though still not the release version

Finally committed to getting one of these myself, the guys at Degritter say it should be with me in September this year, looking forward to it and hoping it ticks all the right boxes for me.
Just borrowed this, courtesy of Kedar ... AudioDesk Vinyl Pro. Degritter has gone back for upgrade to next beta version.
Interesting .. it cleans well enough, I've only had it working a day or so and don't have the Degritter here for a back to back comparison, but I think it's of broadly similar effectiveness to the Degritter.
However it feels a bit basic in terms of functionality to the Degritter, for example, no means to vary cleaning time or drying time (so if it doesn't clean first time you have to run the whole cycle again), also it's definitely noisier both during the cleaning cycle and also when the fan comes on, and it's no looker in terms of aesthetics. Has a bit of a 'previous generation' feel to it in my view but I guess the looks might appeal to some.
Great to get a play with it though and will be interesting when my Degritter comes back to do a full comparison on similar material (two records from a dusty box set for example).
Just a few sec of video as as it's pretty tedious filming let alone watching:

Makes my PHK attached to a Screwfix industrial Vacuum look a bit sad. :( Might try one of those tanks from Amazon though that along with the PHK set up in the living room should go down a treat with my beloved.
There is a separate thread for DIY approaches to ultrasonic cleaning. http://theartofsound.net/forum/showt...ght=ultrasonic
I looked into it but it’s really not what I want for the living room.
Yes the commercial machines are a lot more expensive but are far more easy on the eye, far more convenient to use on the fly (clean one record at a time when you want to listen to it - minimal faff) and a lot more marriage-friendly.
Indeed I don’t see these approaches as competitors at all ...
