Same Gtr/PUPs, cab/speakers?
Some amps excel at this, but the gtr/PUP and cab speaker make a difference also. Recording, when I want sustain, I have several gtrs and amp combinations that I can count on. For what ever reason, a match that works... very musical and harmony rich feedback.

I don't see a grid leak resistor on V3a.
You may also want to put a bit of series resistance at the input of V3a.
Probably list Diode types on schematic.
How can you have an 8 ohm speaker that's also 16 ohms.
a 4x12 cab cannot be wired to both 8 or 16 ohms.
4x12 - 4 ohm speakers can only be wired to 1, 4 or 16 ohms.
4x12 - 8 ohm speakers can only be wired to 2, 8 or 32 ohms.
4x12 - 16 ohm speakers can only be wired to 4, 16 or 64 ohms
an 8ohm 4x12 cab comparison versus a 16 ohm 4x12 cab is meaningless.
first off the same speakers can't be used. throw out that test. four 8 ohms speakers can't be wired to 16 ohms and four 16 ohms speakers can't be wired to 8 ohms.
now, a 16ohm 4x12 versus the same set of speakers in the...
A 4x12 with 8 ohm speakers can only be mono 8ohms using all four speakers. 2 and 32 ohms is not an option.
Using less speakers or wired "Stereo" you could get 4ohms or 16 ohms with 8 ohm speakers.
A 4x12 with 4 ohm speakers can be mono 4 ohms or mono 16 ohms using all speakers.
A 4x12 with...
