RE: Excess Line Voltage vs Amplifier Sound

Yes Sir,

Bad choice of words. I meant going from -55V to -60V but in essence that is lowering the voltage on the grid. But if you look at your response it is adding(raising) the negative voltage on the grid but it lessens the current draw of the tube and the total power supply.

I have modified many Dynaco ST-70 and Mark III amps and they sounded best running the tubes extremely conservative. I alos did very little to the power supply as far as adding Uf's to the caps and the such. It wounded better with almost the stock values. The biggest difference I found sonically was going from electrolytics to film caps in the power supply with oil caps as coupling. Many might not like the sound but I think it sounded softer and more natural.

Again, just my opionion!
