have I learned anything?
Oh yes, you have learned quite a bit. WRT to the Elmasonic P60H PP_Elmasonic_P60H_EN.pdf, it’s a very versatile dual frequency 37/80-kHz unit with variable power and various operating modes. As the book says, a common UT cleaning process with Elmasonic P-series is 10-min auto-cycling between 37-kHz and 80-kHz; then 10-min at 80-kHz. But it’s a very powerful unit. It will heat the tank water pretty quickly.
UT tank power ratings especially for the lower cost Chinese units can be shall we say optimistic. It’s easy to check by how quickly the tank heats up (ultrasonics only) or plug into a simple power monitor such as Upgraded Watt Meter Power Meter Plug Home Energy Monitor Electricity Usage Monitor, Electrical Usage Monitor, Energy Voltage Amps Meter Tester with Backlight, Overload Protection, 8 Display Modes - Amazon.com.
If you plan on serially cleaning a large batch of records, one batch after another, for the Elmasonic P-series you have to manage the tank temperature, i.e. cool it off. You can try what Kirmuss does for his UT tank at shows which is to drain the tank into a container to allow it cool, and refill with cooler fluid, or you can add a pump, filter and radiator. I have successfully set up a few people with a pump, filter and radiator for Elmasonic P-series tanks (Chapter XIV has the radiator details).
Take care and best wishes for the Holidays and New Year,

PS/For those reading who cringe at the details being addressed for full wet cleaning, for new records (and even good condition used records), many people are satisfied with just the Audio Technica AT-6012 brush - Amazon.com: Audio-Technica AT6012 Record Care Kit with Record Care Solution, Brush Pad, Storage Base, and Adhesive Tape : AUDIO-TECHNICA: Electronics used as follows:
- Do not use the fluid provided, it’s now nothing more than water+detergent and it will leave residue. It used to be distilled water and isopropyl alcohol but worldwide shipping regulations have clamped down on shipping flammable fluids.
- Instead, drain out the detergent and 1st flush the bottle with tap-water until no foam, then rinse with distilled water (DIW) and refill with 50:50 distilled water (DIW) and 70% or 91% isopropyl alcohol (IPA). Do not use rubbing alcohol it has other ingredients that will leave residue.
- Wet the leading edge of the brush (the brush is directional) with the 50:50 DIW/IPA solution, then wipe the record (while spinning) with the wetted edge, and then roll the brush to dry, as shown in this video - https://youtu.be/eQIFbCc015s beginning at time 3:05. If you watch the whole video dismiss applying the 5-drops to the top of the pad.
- Note that over time, the pad will get dirty, and it will give back more than it removes. Just flush the pad with DIW (spray bottle works) and then finish with wetting the entire pad with the DIW/IPA solution to speed up drying the pad.
