Hey all,
Just picked up a used Mark IV combo and have been spending some time trying to get it "dialed in". A real tweaker's amp! Anyways, I've read good things about a Tung-Sol reissue 12AX7 in V1 of this amp and I think that may give me just the right amount of growl to the OD in R2 channel that I'm trying to achieve - however when I tried to put one in there it didn't seem that it would fit without possibly scratching and ruining the tube. It seems that the Tung-Sol is of a slightly wider diameter than the Mesa tubes as well as many other 12ax7's that I have. The metal protective housing for V1 seems a bit too narrow to accomodate it. Anyone else have this experience? I have read of people using this tube in V1 of a Mark IV so there must be something I can do!
Thanks a lot!
