Tima: the specs for his 120H say 200w/800w at 37 kHz. Any concerns about the higher power setting at such a low kHz? - Jim

Jim:

First, it's a 12-L tank; and the larger the tank, the more power required. Second the 800W is pulse power which is a very short time cycle and the 200/800W https://www.elma-ultrasonic.com/fil...e/Elmasonic_EASY/PP_Elmasonic_EASY120H_EN.pdf pales in comparison to the dual-frequency 37/80-kHz P120H which is 330/1320W that @tima uses for cleaning - https://www.elma-ultrasonic.com/fil...geraete/Elmasonic_P/PP_Elmasonic_P120H_EN.pdf.

Thanks, Neil. I hadn't seen the PDF.

Hi Jim -- no concerns based on experience with the units that I use.

The Elmasonic S 120H (37kHz) I use for rinsing is rated the same as the Easy 120H: 200W effective ultrasonic power and 800 maximum Watts for peak performance power.

The Elmasonic P 120H (37kHz/80kHz) I use for washing is rated 330W effective ultrasonic power and 1320 maximum Watts for peak performance power.

edit: guess I responded before seeing Neil's.

That you two are in agreement matters, so glad you chimed in. My head and hands have been busy with things other than record cleaning of late, but I'm still of the opinion that if I want to step up my game from the VPI pre-wash >Degritter multi-cycle with three tanks, following in your footsteps is the way to go. I'm at the point where if there's anything I'm not removing, it's the occasional boulder so stuck or wedged my methods just don't touch it (brushwork focused on the area often will). That's why my ears perk up when the discussion involves the lower frequency machines which I suspect might address the problem.

Nice. Any time you choose to explore beyond a single-slot machine approach, we are here to help. Fwiw, the first post in this thread now includes pointers to some of the specifics about my system.

Thanks, Tim. I have looked through the thread more than once, so have some understanding of what you've done and know if I decide to assemble something (very) similar, you've pretty much put together the manual. So, where is "upper midwest?" I'm in the KCMO area these days, but went to high school in Brookings, SDAK. I suppose we considered "upper" to be Fargo . . .
