So I am really having a laugh here because I'm trying to figure out where Channel 2 on a Fender Model T Reissue is coming from.
Some people have claimed it's basically a Mig 50 preamp
Others have claimed it's JTM in origin (though I don't hear it)
And the shop I was about to contract to mod one of my Randall MTS modules wanted an SLO donor.
My ear tells me the SLO origin is actually correct. But in my limited and still very novice eyes, the first thing I notice when looking to Channel 2 on the schematic below, is that it is still very much a Fender circuit.
I think a lot of these people are mixing up the reissue with the original Model T which was bassman derived, which is part of the lineage of the Mig50. Any input is appreciated!
IMHO, very much the usual setup: Marshall 2203 with added gain stage at input and couple of other mods here and there to tinker the response and gain. 18k cold cathode bias on the 3rd stage is an intermediate between 2203's 10k and Soldano's 39k. (And yes, SLO is also a 2203 with input boost and few mods).
Low cathode bypass capacitances (for treble boost), JMP era tonestack circuit, and cold cathode bias stage are dead giveaways that it is not a classic Fender circuit.
MIG50 is a Marshall 1959 clone. (The model with parallel bright and normal channels and JTM era style tonestack).
Bassman 5F6A is merely what Marshall based its first JTM series amps on. Addition of bright channel, emphasized high mids response overall, less mid scooped response of the tone controls and master volume are all Marshall additions to tweak the design to something quite different. So is the later invention to cascade the - formerly parallel - channels for higher gain.

Sunn made the original Model T. It was a powerful clean amp. Much later, Fender bought Sunn. Fender's Model T looks nothing like the Sunn original. Only the name survived.

Thank you, I was able to cop what I wanted out of the Model T RI enough by just turning the gain down on my SLO\2203 hybrid setup, did just what I wanted without having to spend a single penny
