I will try the unplug suggestion, will be using my back-up amp ( a ss design, which does make for a lot less nervosa) for a week or so.
Last night, I was pleased to hear that the tube amp was in fact sounding a lot better, the increase in power was still very evident ( and strange) but the overall SQ was fuller and less bright. I moved a power cord off the preamp and replaced it with another brand...this could have helped.
Here's the interesting thing, my ss amp puts out 250 watts/ch into 8 ohms...and nearly doubles into 4ohms, my tube mono blocks put out 48watts/ch into 8 ohms and not much more into 4ohms...yet the tube amps sound FAR more powerful than the ss amp. ( Yes, the tube amps have massive transformers, while the ss amp has slightly smaller transformers..and the tube amps are mono blocks, while the ss amp is a stereo amp...but the power output in volume is strikingly different...and adverse to what one would expect!)
