I'm thinking ImPasse -- I have a bunch of really premium 6SL7 and 6DJ8 laying around unused, as well as a suitable power transformer, etc...

Manolo47 -- what are you using as a preamp into your F4?

put second Graetz + C bank , and make double mono

then you'll have improvement


ECO-S1EP153BA Panasonic Electronic Components | P6890-ND | DigiKey


but - be aware that DC voltage will rise slightly (less sag due to less load per xformer) , so with 25Vdc caps , you're there , in danger zone
Whatsa "Graetz"?
