So I've got my Mark III Fully Loaded Blue Stripe retubed with a brand new set of Tung Sol Pre Amp Tubes. They sound pretty nice and lively but the amp has a nasty harsh buzzing no matter what the settings even with treble/presence/high eq all on zero.
The clean channel sounds beautiful and the rhythm aint too bad either, and I remember only a few months ago the amp was able to get really dark and smooth but not anymore.
Could power tubes cause this harshness or is it something more serious like needing a cap job?? It is from '88 i think so Im sure it can use a tune up.
Does this harshness just sound like power tubes or something else?? Also Im running through a vintage Orange 4x12 which is really warm.
Thanks
Chris
