I'll think it will become an integrated amp. With direct-in or something as an alternative.
As usual I started by giving the transformers (Transformers by https://jr-tubeaudio.com/) a makeover. With some hammerite and I gave them my Magnequest EXO-800 brass shrouds. (Exo-800 are small enough to put under a chassis)
Choke is a One-Electron UBT-1 (Primaries only ofcourse) that was the odd one out. (I once built a three channel 6c41c for my home theatre. But only ever used it for stereo)
Gave the covers a coat or two of Urethane because I hate polishing brass since my stint in the South African Navy 😉

The Salas Pre-Amplifier with 6P43P-E came into my mind because John who wound them for me said you lose some gain with the tertiary winding.
I love my Salas but wanted to try a much much cheaper tube (6v6 even new ones aren't exactly cheap. Not expensive but certainly not cheap)
I like the subchassis thing so decided to hack my rh-84 boards for the purpose of building a 6p43p on there.

Aesthetically, a very beautiful combination of colors. The hammerite and brass color is perfect, I love it! Best wishes for the rest of your build!
Not working yet. Because I hacked a RH-84 board to build the pre on and I must have miswired something...so just a glamour shot for now.
Pre-out for subwoofers. One Electron UBT-1 as power supply choke. All DC-Link polyprop in power supply. Cathode feedback output transformers from https://jr-tubeaudio.com/ (South Africa). Bronze covers from a Magnequest EXO-800.
Output transformers have a darker hammerite because the lighter green did not work well with the brass.
