hi Steve acouple of days ago I had the board out when doing initial repairs and when reinstalled notice crap from the connector and when I inspected the board all 3 pins were iffy and totally loose and wiggled to the touch. I did reflow those a couple of days back. When I was fixing the effects board i noticed the only ground path was pin 2 of the molex.. don't really like that engineering but it is what it is. When I was tracing signal I had the connector apart but made sure I jumpered the ground path into pin 2. I swapped the differental transistors to pnp bc556 to no effect seems the same. maybe a little quiter. have not changed out q3.
