I love my KOMA field kit and field kit FX (I got them 2nd hand) but my field kit mixer has a broken channel 1.
I've measured on the board and the working channels (2-3-4) have around 4 V on the center pin of the tone control.
However, the broken / dead / channel (1) measures 6-7 V on the tone control center pin.
I fear the mixer might be out of warranty - but if anyone here has solved a similar problem I'd be very grateful to hear about it. (I'm thinking along the lines of: if the buffer-amp is broken, possibly you could add an extra LM324 just to handle channel 1 input?)
