Power Supply
I had my tech guy do a partial power supply rebuild on one of my EL84 amps using ASC poly caps in the power supply. He rolled his eyes at me even worrying about the "sound" of something not in the signal path.
The amp had a hum after that and he could not hear on his test speakers.
I only used it for a few hours or so. I thought he had changed some of the coupling caps to poly as the amp sounded very different than every one of the vintage amps I have. I took off the bottom plate to find out he did not change any coupling caps.
The amp had more bass than the old vintage electro caps but sounded slower and had change in tone. I did not like it.
Can power supply caps affect sound? Not just smothness and power but tone?
