Although I have an H100 in my stable of Hammonds, I don't recall the amp topology offhand. As Jay mentioned, they do have a rather high input signal requirement, and most are balanced in as well. The other Hammond biamps I've "done" (from tonecabs) have a first order XO around 200Hz, with an extra channel for the reverb tank. While in general they do very well on the low end, I'm unsure of the HF response, as they only needed to go so far.

If you just want the amp, I've got at least two "spares". PM if so. From memory, I think the tonecab biamps (HR40 etc) would be more conducive to hifi. Have a few of them too. 6V6 PP beats 6BQ5 in my book, but they're beefy monos, so make some room...

The H100 was an initial venture into hybrid SS.\

Added;
Since the H100 was all internal, it should accommodate low level inputs OK, unlike the tonecab amps that were fed by a balanced pre from a B2/B3/C2/C3.
