I inherited from my dad an old Electric Mistress, the 18v, two 9v battery version. I love it to death but it has given me a ton of issues in the past, including dying twice and being resurrected by a dedicated repair shop near me which no longer exists. They cheerfully replaced my busted filter matrix switch and added a battery bypass, so I could use a power adapter without frying the board, which I have for a long time. Recently the adapter pin cracked at the neutral end at the base, and I continued to use it until I smelt a burning smell from the wall wart, at which point I immediately junked it and disconnected my mistress.

Before that, I was getting a lot of noise. A LOT of noise. I could hear the oscillators (no biggie), but the unit was also generating sweeping sine tones which were affected by the controls, same as the tone, which were as loud as the signal going through it. It was kinda cool, but I began to worry if the SAD 1024 or some of the other IC’s in it were going… it was troublesome because I know some of them aren’t made any longer.

Going to see if I can dig up some 9v batteries and see if I can get it to work…

Any advice/diagnoses?
