Vintage amp restoration and Beyond

[GoldenVulture]

I can take it up to some really loud clean sounds at about 50% pre-amp and then turning up past that on either channel they start to overdrive. The KK pre channel [1] has a mad amount of gain and it overdrives the valve into distortion which is unusable above about 80% gain [ for me ] . It gets really noisy from there up and loses it's tonal balance. I haven't really got into hammering it much because of the O.T. overheat. It's going to be hard to get Power Tube breakup because of the high plate voltages.
