Peavey 6505 Plus Head Output Transformer Imbalance

Hello:

I'm looking at a Peavey 6505 Plus head for someone and I'm finding the plate current is slightly off from one side to the other by about 4mA.  I checked the tubes and they are all matched and test the same on a Heathkit tube tester.  I measured the resistance of the output transformer and one half is 30 ohms and the other half is 40 ohms.  Doesn't seem to make too big of a difference on the waveform until the point of clipping in the output section, then the top half of the wave starts to clip a little bit before the bottom.  I highly doubt the guy plays it loud enough to reach that point.  The B+ at the plates is the same on both sides.  Is this enough offset to be concerned about.

Thanks!

4mA on 40+mA tubes is "nothing".

Button-up and give him the bill.

Asymmetrical clipping is something people love about tube amps. Most overdrive pedal mods are all about that.

Cool, thanks for the replies!
