The way I cut the amps power in half is by switching the output tubes to
triode and adjusting the volume to have the same SPL in pentode.
I understand the theory but I would love to hear your opinions on what if
any differences can you hear between the 2 modes. I know this subject has
been beaten to the ground but the theory always obfuscated the sound changes
for me. Can we just talk about the sound in your words? It will help me
plenty. Thank you.
There is a completely different change in sound depending on whether the
amplifier has negative feedback or not. You need to tell us whether the
amplifier in question uses negative feedback or not before we can
comment on the sonic differences between the two modes.
