I have had a Conn organ tube amplifier since around 2002 or so. With only a couple small circuit mods and a quad set of EL34s this thing honestly blows me out of the room. But, its fugly.
The same amp another member has is here:

Despite people saying the output transformers are mismatched, they measure physically identical and they appear to be equal in frequency response as far as I can tell. The only difference is the 6V6 stage is powered by a big dropping resistor. That is the modification I did was disconnect that, and powered both channels directly off of the 400V supply so both channels perform equally.
The reason I am posting this thread is I like the sound so much, but I hate the chassis just as much, I want to transfer the iron at minimum over to a new chassis, MAYBE the circuit design as well, and that is where I ask for your experienced subjective opinions. The circuitry like i said sounds great to my ears, BUT, I am sure there is room for improvement so I was wondering what your thoughts are on the circuit? or if there can be an improvement sonically to the amplifier?
I posted a copy of the reverse-engineered by me schematics of the amp. I cant find the original. Also, I cant really find the phase splitter topology anywhere either, at least not quite like that implementation.
any thoughts?
