The Phase Inverter creates two mirror image signals that are 180 degrees out of phase to feed to the Power Tubes.
Even with the Celestion Seventy 80 speakers, this is one loud combination.
The Low inputs have their guitar signal cut in half by forming a voltage divider with the two 68k Grid Stopper resistors.
They based it on the Fender Bassman amp, but used larger speakers and kept the cabinet back closed.
The other thing that might be a deal-breaker is there is no built-in reverb either.
