Spider Valve MKII 112 Bogner - Overheating
paramero replied to Markfothebeast's topic in Spider Valve
I already bought a duet Mesa/Boogie 12AX7 Preamp Tube and some Mesa/Boogie 6L6 STR 440 Power Tubes-Matched Duet for my SV MKII, 40. But I confess that I am afraid to make the change because I do not know if they are compatible. And I don't know how to do the Bias.
