Sorry to cross post, but the guys in the workbench said someone here might know. So I bought a 69 Super PA a few months ago, and I’ve been trying to tune it up a bit. One of the issues we it had a wonky replacement power tube socket. So I bought one that I thought was more correct for the amp. Socket - Belton, Micalex, 8 pin octal, MIP https://www.amplifiedparts.com/products/socket-belton-micalex-8-pin-octal-mip But there seems to be a little plastic lip with a diameter of about 30MM. The inside hole in the amp is 28.2mm. About a 2mm difference. Did i just buy the wrong tube socket? Everything on amplified parts seems to say "1 3/16" to 1 ¼" chassis hole diameter. So I'm guessing this is the wrong tube socket. Does anyone know where I could get a replacement for my 69 SuperPA?
