There should be 7 tubes in that head, the 3 small are the pre-amps, the 4 large are the power tubes. I have no Idea if your amp has bias test points or trim pots I can't seem to find a schematic for it. Best for You to take it to a local Tech and have him replace the tubes. Buy from Ebay, you should be safe with CP (current production) tubes as they usually don't counterfeit these. Get what I told You 2 Tungsol 12AX7's and One Electroharmonix 12AX7 for Your V2 cathode follower position and a Matched QUAD (4) SED Winged "C" EL34's Take these and have Your Tech install them and Bias Your amp at about 65% Dissipation at idle. Also TELL him the Electroharmonix is for the Cathode Follower Position.
TWIN
Mine is the 50 watt version so it has 3 + 2 tubes not 3 + 4 (100 watt version).
So I should get:
- 2 Tung-sol 12AX7s
- 1 Electroharmonix 12AX7 (for the Cathode Follower Position)
- Matched TWO SED Winged "C" El34s.
My wallet just squealed a little bit. I also need a cab =(
