Hi Guys
It is actually very simple why a change to the power supply filter cap values effect the tone: the power supply is the other half of the signal path.
This is exactly why Galactic Grounding is so important, and at the very least, why having filter caps close to the circuits they support is important AND why the first filter cap is ultra-important.
The main filter is the first defense against hum in the amp. It is where the pulsating DC is converted into as flat DC as possible. It is the filter that directly supports the output stage in most amps and therefore it carries the highest amplitude signal currents. This makes the capacitor impedance vital to performance.
It is no surprise that the updated amp has a big sound compared to stock.
Yes, lower-value coupling caps are the fix for many woes in tube amps.
