Wow! Thanks Tubeactive! That info is more than I could have hoped for. I will definitely try those mods as it sounds exactly like the results I was envisioning that I wanted. I have several little SET amps so I had a good idea what this one should be capable of, and it just wasn't there. This little amp fits really nicely into a convenient spot in my secondary listening area where a larger chassis like my ST-70 or even the Magnavox 9302 just won't fit. I will be stoked to get it sorted and sounding good. I am not well versed enough with tubes to be able to recognize what was going on, but I have tried several different things suggested previously with only slight to no impact on the drive power of the amp. Yes, I did end up having to put resistors in my heater drive circuit to tame a really high heater voltage. Now that you have given me a better understanding of the gain situation, I will begin putting together a parts order and get this project moving.
