Hello all, and thanks for letting me join.
Working on an old MXR Distortion + I had to replace the stomp switch which died (original was a Carling) .
I also installed a 9v socket...
Pedal seems to work fine... except for sguealing sound...
Before you ask, same problem on battery.
Pretty simple circuit, all i can think of is one of the 1nf tantalun caps not doing it's job - any ideas?
P.S. On the scope it seems to clip the lower half of the wave a bit before the top - diodes not matched? Hardly matters I guess...
Thanks in advance for any help.
