These are the transistors that shut the audio outputs when the power is turned off so you don’t get a loud pop. The machine even works without them. When there’s current leakage in them however, you get distorted audio outputs.
Thanks bro
I'll have them checked out, but I'm afraid they're more degraded my juno 60. I can't put the level above 6 on it and use the chorus, it will distort.
No real problem though, as the J60 output is quite hot.
