Happy Friday, Lemme first start off by saying that I have searched this site for info., and I think I may have pieced together an answer to my question, but not 100% certain. I have acquired a used Vic Trem d' la Trem. I asked the previous owner whether it's fixed or cathode--5E9 or 5G9. He told me it's a 5E9 fixed... Well, I happen to at least know that the G9 is the fixed, so now I'm even more confused. I think I've located the Cathode capacitor (Ohmite 20J250/E), but again not sure as I've been piecing together bits of info I've found on the interwebs. I also tried asking Mark, who told me it's easy to determine whether fixed or cathode, and that was about it for our conversation. I'm not an amp guru, but I'm trying to learn all I can, so if someone could please lend a hand I'd greatly appreciate it. Thanks in advance.
