DC Filament Wiring
Nothing like resurrecting an old post...
I have but one question:
How should I wire the filaments of an ECC83 and ECC88 when I have a regulated 6.3V filament supply? Here's what I'm thinking (which guarantees that its wrong):
Pin 4 (f): +6.3VDC
Pin 5 (f): PSU Ground
Pin 9 (ground): PSU Ground
I've only used AC on the filaments before, so I'm confused about this (obviously).
