hey,

so here is what new from last time.

i replcaed all the electro. caps. the power filterings caps were leaking so i changed everything while at it. some film caps were actually breaking when i touch them (like the covers are turning into sand) so i changed most of them as well.
one 4558 was showing no voltage on pin 1 so i took it out and installed a new one. from some reason it reads the right voltages now.

i took off the solder from most of the parts and resoldered them, this took me almost an entire day. now the board looks a little nicer. i also changes some wires that were going to break with new wire.

i decided to messure the voltages at the diodes, most of them do not have any marking on them but i guess they are clipping diodes for the gain stages and some are zener diodes? i also found two that look like germanium but i am not sure.

i did find two clipping diodes (linked together in different direction) that had 0 reading on both sides of them with ground. could this be the problem?

i have pictures, sound clip of the problem and volatges in my original post http://www.diystompboxes.com/smfforum/index.php?topic=44418.0
