Princeton Reverb Tubes
Question:
How many tubes is a classic Fender Princeton Reverb Amp supposed to have? Mine has one big fat tube called a GZ34 and two smaller tubes called GTs and four empty sockets which look like they were for much smaller tubes. The amp is model number AA764. It has a pedal switch for the reverb and the vibrato. Quite a loud beast, actually. I use a 1966 Mustang and a cheap piece of junk Jap guitar loaded with a JB jnr, a Shaller humbucker and a Gold Lace sensor. I also use an Ibanez slim-line electro- acoustic which is virtually unplayable. I use a Zoom 1010, which, IMHO, dirties a guitar’s sound considerably, but I can’t afford individual digital delay, chorus, and distortion pedals. Anyhow, if anyone could give me the low down on the amp, tell me if it should have more tubes, what years they were made and roughly how much it’s worth, I’d be appreciative. The amp is black vinyl, with a silver and greenish mesh face, with Princeton Reverb-Amp in green letters written on a silver control surface. The knobs are black with white numbers. There are two input jacks and a red, jeweled looking power light. Feel free to reply via e-mail. Carl Grindley

Are you sure those aren’t just the aluminum covers for the miniature preamp tubes? Unplug the amp and try to remove one of them, if the amp works at all there’s probably a tube inside it. –mic– — — Mic Kaczmarczik — Unix Services, UT Austin Academic Computing —

The silver panel and ‘Princeton Reverb-Amp’ logo indicate it’s from ‘68 to early 70’s. If it works with four empty tube sockets, it’s been heavily modified, with little $$$ value. The original tube complement for that model, from RIGHT to left, is 7025, 12AT7, 12AX7, 12AX7, 6V6GT, 6V6GT, GZ34 (sometimes 5U4GB). If it really works with four empty sockets, there’s no point putting tubes in the sockets, the original circuitry for those tubes must be gone. RF Robert Fries 415-988-9475

Unless it’s been removed, there should probably be a tube chart pasted to the inside of cabinet (usually to the right of speaker, looking from the back). I believe the two smaller tubes are 6V6’s. If the four other sockets are really empty, then there’s no way your amp would function. If it looks like an aluminum cylinder, push it up and give it a half-twist to remove it. The tube is underneath (a combination of 12AX7s and 12AT7s).
