I think the 50w small head has a resonance control; the 100w full size head does not.
50w had MIDI capability too.
all true........
along with the addition of a quarter inch connector for the footswitch of othe 50w vs a 7-pin cable of the 100w. There were numerous issues with the 100w 7-pin cable.
50w has a headphone output the 100w does not.
100w has larger Schumacher transformers than the 50w.
Channel 1 on the 50w breaks up later with the gain knob
Channel 2 has more gain on the 50w than the 100w
Channel 3 on both are virtually identical
Both amps come w/ JJ's (although my early 100w came w/ Sovtek/EHx mix, which I like more)
Both amps were meant (and sound the best) when ran through a 16ohm cab
The previous was mentioned by Howard Kaplan when he was explaining the differences between the two amps over at TGP, not necessarily my opinion. However, I do find all of it to be true with my amps.
I use the RJM mini amp gizmo to make the 100w midi compatible.
