This model uses solid-state rectifiers rather than tube rectifiers. This is the phase inverter and vibrato tube. Advances have been made with regards to the production of tolex amps and it appears that much of this information can be applied to late s tweed amps as well.
The Princeton Reverb is identical to the regular Princeton circuit except for two key additions. Jason Isbell has been known to plug a custom Tele directly into a Princeton when touring with his wife, Amanda Shires. Third tube is the driver and reverb recovery amplifier. Fourth tube is the driver and reverb recovery amplifier. Many earlier Fender tube amps used rectifier tubes.

Greg was passionate about Fender amps and his knowledge, and leonard insight and humor will be missed very much. It would have been very costly to destroy these units so two remedies were implemented.
Fourth tube is the driver and vibrato modulator. Again, the amp sounds great to me no matter what it is so it doesn't matter a ton. Here is a list of the first letter showing the year of manufacture. The machine that stamped the serial number into the back of the chassis got stuck on number A and a lot of pieces were stamped with this number.

Then leave it in center-position. With Fender, this is always somewhat arbitrary, but if the logo is original look at the scrwes holes beneath I would estimate or and a replacement power transformer. Please check the fields highlighted in red.

Fourth tube is the phase inverter. These were almost always at the extreme left of the chassis, when looking at the rear of the amp. Vibrolux and Vibrolux Reverb. Third tube is the reverb driver.
Happens all the time with Fenders. Good luck reading some of the hand written ones. For some reason, folks are willing to poke their head into tweed, blonde, brown and blackface amps, but not into silverface amps. They said it was a Silverface that had been Blackfaced.

Early Fender Electric Blackface amps from and some into early did not have a Fender Logo on the grillcloth. Ink date stamps are notoriously unreliable, and although they look like dates they sometimes don't indicate dates at all Check the serial number against the list here. Second tube is a driver stage for both channels of preamp, beautiful dating specified.
- Interest in vintage Fender amps really took hold about years ago.
- But if you also swap out the output transformer for more power, these two mods in conjunction will create larger, louder sound for gigging musicians.
- Princeton and Princeton Reverb.
These modifications are making this research more difficult for a couple of reasons. The progress of this type of work is slow, hence the long hiatus, however, a lot of new data have been collected regarding Fender amplifiers, including production numbers. Can you guys be as helpful with that? Oh ya, here is that missing number Big Mike. They paid for a replacement though with no hassles.

The following charts are the revised dating tables for Fender tube amps. In addition, the dating-by-serial number tables have been revised and are more accurate. What info would I need to post to get some help dating my Princeton Reverb? But the Princeton Reverb is the stuff of legend.
- As others have mentioned the rest of the codes and serial number will tell the tale.
- Make sure you get the amp vetted by a competent tech, especially if you're going to gig it.
- Solid-state rectifiers do not wear out as tubes do, nor can they be replaced by the user.
- Here is where it is located on the back.
- Fifth tube is the pre-driver.
- Third tube is the driver and vibrato oscillator.
One, of course, is the reverb unit. Bias should be adjusted when tubes are replaced.
