"What I don't want to end up with is an amp like the HK A300 or A500"
That's exactly what you're proposing to build, at least in terms of the output section. The Cit V is essentially a more powerful version of the A500 power amp topology. FWIW, I just finished testing a prototype using the A500 as a foundation, and the results were very, very good. I changed the 7355 output tubes to a 6L6 variant, grounded the cathodes and applied fixed bias. THD/IM and frequency response were excellent, and I believe performance will be even better in the final build ('SL7s and 'SN7s in place of the minis). Just to be clear, this is the A500 power amp/power supply only, no preamp or tone controls. I was never satisfied with the control sections of the amp, so it's being modernized on a new chassis without them.
