Here's a good sounding circuit

My 6B4G PP amp uses 4P1L input and drivers. Absolutely my favourite amp, and 4P1L is a little miracle. Klaus in Russia posted some circuits - see attached link.

I'd take the power supply and filament supply outboard, and the 4P1Ls will need DC filament supplies with heatsinks. But this is an all-DHT design and serious hi-end sound.
