Hi,
I'm trying to repair a Lafayette echo verb.
The main two problems are:
1. There's a strong distortion when I plug a guitar to both instrument and mic inputs.
2. There's strong hum noise while turning up the reverb pot.
I've already replaced the four electrolytic caps, replaced the filtering diode with diode bridge, replaced the four transistors with new ones and nothing seems to make any difference.
Since I can't find the schematics for it I don't know what else should I do.
Any suggestions?
