Hi.Nice done job.
Some comment on your wiring:
(1) input signal wires -
for EACH channel as in your case, I'd use two RF coaxial centre conductors, run as TWISTED pair (one as signal go & the other as signal return, so 100% balanced). I would shield this twisted pair in ONE only common overall screen sheath, to reduce the capacitance always induced btwn the signal wire & the shield by half.
I would also ground the overall shield sheath only at the input stage local ground point, leaving the other end at the input jack UNgrounded. The idea is to make sure any stray EMI noises be drained
away affectively. This is particularly crucial if ground noise level
of the pre-amp hooked up to your power amp is not absolutely zero.If the input signal wires are much shorter than what you got now,
I'd go for just twisted pairs without any shielding which affects the sonics.(2) bundling up signal cable -
I would run signal cables of each channel separately, away from
any HT, LV power running cables. IMO, bundling up cables is a old-school practice for "tidy & neat" layout looking? It is pretty 'unhealthy' sonically.I love your idea of using bare solid (min 4N Ag purity, I hope)
in LOOSE "oversized" sleeving. This surely enhance the sound.I'd surely try your tweak of 'starving' the signal valves with
lower heater voltage & see how it would better the sound.Good DIY listening
