]Hey guys I’m new on here. I signed up after I bought the “maleficent mids” & “ProCyon” PCB’s. So this will be my first post on here!
Im hoping that you guys might be kind enough to offer a bit of advice regarding a TS-9 reissue im having problems with?? *I’ll try to be brief!
-After removing/replacing components and reworking solder joints several times, I’ve lifted solder pads in a few places. Normally not a huge deal (just expose a trace/bend the lead etc..) however these are “solder island” type lands unconnected to any copper traces and contain the leads of the clipping diodes & 51pf cap on the first damaged land and the .047, .022uf caps/4.7 resistor etc, on the second damaged pad. I had repaired it and it worked fine for over a year. Then one day it stopped producing sound.
**So I laid out some copper adhesive and replaced the diodes/cap at the same time with new ones. It’s generating signal now.. However I’m getting a lot of noise/hiss & the overdrive is really fizzy now. Any idea what to do? I wish I could just replace the entire PCB but nobody sells one with the buffered bypass switching.
**My suspicion regarding the cause, is that the diodes I used to replace the originals are either the wrong type and/or specs and they’re effecting the op-amp behavior as well as other parts of the circuit/forward voltages etc. You’re Thoughts?? I’d be very grateful for any advice!! I’ll post pictures highlighting the areas I’be been referring to
