Hi, I'm repairing this Chinese SG2701B01-7 panel. There isn't much information about it. The original part for the panel is a CSOT CS601C regulator. I can't find anything commercial on Aliexpress; there's only the CS601 without the final 'C'. They claim it's a variant. But will it be compatible?

CDS‑200B ultrasonic cleaner - AKA James Ultra 7050 etc.
There are many versions of cheap Chinese ultrasonic cleaners, and a fair few share this design, with a removable tank with handle. There are also fixed tank versions which look to use the same basic layout and presumably the same PCBs.
I picked one up "spares or repair" on ebay, and the cleaner was dead, but the fuse wasn't blown.
A quick diode check revealed D7 was shorted. D7 is a 12V 1/2 Watt Zener. I had one in my stash, so this was about as close to a "five minute repair" as...06-23-2025, 03:22 AM
