I see that I can save on current consumed by switching up to the LED mod vs the standard bulb. Seems like a good move rather than replacing the old burned out bulb. This has me thinking, I don’t use the phono or tape inputs that belong to the PC-6 card, could I get away with pulling the 12AX7’s on it without modifying the PAS and achieve even better filament current savings and not adversely affect the line card performance ?

Re: PAS Filament current
You could pull those 12AX7 tubes on the phono board - BUT - then the other two line stage 12AX7's would be working at somewhat higher voltages which *could* shorten their life. What I might do is put a couple of cheapie Chinese 12AX7's on the phono board and save the better (Telefunken original ?) 12AX7's that are on the phono board now.

Re: PAS Filament current
Seemed like a good idea... I think I'll leave the tubes alone, and just replace the burned out bulb with the LED kit...
