OK comrades...MIG 100B and MIG 100H Differences?

[tim]

I have a Sovtek MIG 100B on the bench that someone tried to modify the front end in. I am trying to determine if there are any differences between the B model and the G model. I can't seem to find any schematics for the B but there are G model schematics everywhere. Trying to piece together the parts left on the PC board and match it with what the G model says should be there isn't coming together real easily.

Does anyone know if A) there are any differences between the two models in the jacks/preamp circuit and B) if so, what are they?

Thanks...

Edit: It appears the B model is actually a bass amp, nyet?

Well, they're very similar to Marshall 1959 and 2203.

Some have the two separate channels, while the others have the front end cascaded for more gain like the Marshall 2203.

Some have the pots mounted to the chassis, others have cheap plastic pots mounted to a metal bar connected to the tag board.

I don't know if there was any reason for the changes or model numbers to distinguish between them.

New Sensor had it...I will upload it to the schematics folder later on...
