My PAS-3 seems to use only pin 5 (with pin 4 grounded and pin 9 not connected) on PC-6. One tube uses 12VDC positive and the other negative voltage.
On PC-5, both pins 4 and 9 seem to be not connected to anything, with only pin 5 used for positive and negative voltage on alternate tubes. Is this correct?
I'd appreciate any help you could give me.....a diagram or just an explanation would probably do - before I go and cook something that I don't want to.
Also, does anyone know how to wire up 12AX7's in a guitar preamp using ~6VDC. I can't figure it out and I can't find anything on that subject online... eg. what connections do you make for pins 4, 5 and 9.
Do you have positive and negative voltages on the same tube ?
