Can't speak to the 60w combo, but I had an HT100 head for two days once. IIRC, it's the same circuit.
Couldn't stand it. The diode clipping of solid state gain stages was an automatic deal breaker.
I wanted to like it as a back-up amp, but just couldn't get a tone I could live with.
I don't mind having a B rig, but that was a C-.
YMMV.
