Hi, my Mesa Boogie V-twin has gotten noisy as a train wreck and after a visual inspection with a jewelers glass (my eyes no longer cooperate on this small stuff) I am assuming that according to this schematic C2 is simply a bypass cap...its the one that looks to be broken (they seem to be glass monolithics or similar)...

I am supposing if its simply a bypass I can just use a ceramic since I cannot locate anything like what they used...


Sorry about the gif schematic its the only one I could find...and while I'm in here any suggestions to clean up this circuit would be welcome...right now the outputs are acting really funky...the "mixer/headphone doesn't really work and the amp vs. power amp outputs are not consistent either...

For white or thermal type noise I'd look at the active components first , the tubes
I.C. 's hope they're socketed . Having some little amp that you can use a probe to tap off the
circuit and listen to it along the way to see where the noise starts may help  [ no scope ? ]
 
C2 is a coupling cap and I wouldn't use a ceramic cap there. Use a good quality high voltage polyprop like Orange Drop 716 series or a mullard cap.
 
Yes, I caught that last night, the confusion was there are only 2 tubes not 4 I was reading it wrong...am I right to assume these are glass dielectrics in this? very small bead types I have never seen before...
