the cap is a rf feed through cap and not a bypass if you see voltage goung through it and you want to check it simply remove it from the circut and test for resistance accrost it, it should be infanant, if you see any resistance other than infanant than the part is shorted, being that it is a homebrew amp and if it is shorted than i would assume that it is a under rated part as in a 10,000 volt part where it should be a 25,000 volt part.
hope this helps. |
