dannybuoy Posted January 28, 2013 Posted January 28, 2013 Interested to know how come you have this - have you ripped it out and put your own preamp in?!

[/quote] Not at all. I bought it from Ebay several years ago. It had a damaged valve socket, which I have replaced. The original owner had damaged it and so the whole board was changed.
Mr. Foxen Posted January 28, 2013 Posted January 28, 2013 (edited) Know what input voltages it wants? Edit: I spot the heater one n the board, kinda guessed that though. Edited January 28, 2013 by Mr. Foxen

Edit: I spot the heater one n the board, kinda guessed that though. [/quote] Yes heater is 6.3-volts. HT unknown and I've not been able to get a schematic. One would need to get hold of a full amp and measure it. DI out section of the board needs +15/-15-volts.
Mr. Foxen Posted January 28, 2013 Posted January 28, 2013 Any sort of ballpark idea? Like are they running on proper voltage, or starved plate style?
