I bought a Mark IV short head on ebay and I'm not sure if it's a version A or B (haven't receive it yet)
I want to order new tubes but I have read somewhere (can't find where..) that there were at least one of the
preamp tubes that should be different in them...
Anybody can help me on this before I order my tubes!?
