I'm working on a Bassman reissue(not the LTD) that has a fixed bias. Had a bad power tube and replaced the pair. Checking the bias and it's down in the 28-29mv range. Checking further, I have -55 at C- and 485 at B+ (good as per the schematic I have) but the voltage at TP7 should be 257 and I have the same voltage as at B+(485). Is this a problem with the output tranny? I don't see anything else in that circuit that would affect that.
Thanks!
Thanks!
