Hi Guys, I'm now the proud owner of a '67 Super Reverb with alnico CTS speakers. It sounds GREAT! Some of the tubes need to be replaced as there is a rushing sound in the backround (Almost certainly a bad 12AX7). so, I'd like to get some suggestions as to 1. the if money was no object tube choices 2. The only current production choices 3. where it may make sense to put in NOS stuff and where current stuff is fine. I figured this might be able to help most people with BF Fenders. Thanks in advance, Paul BTW, I really love this amp.
