1967 Fender Princeton Reverb, sn A18544.

A Fender Princeton Reverb, August 1967 issue. The amplifier works fine, including reverb and vibrato. It's quiet and was repaired around 1995. 

Here are the details:

• 1967 Princeton Reverb chassis AA764: 2-6V6 output / 2-12AX7 / 1-12AT7 / 1-5U4 rectifier, 12 watts
• Tube Chart Date Code QH (August,1967)
• sn A18544 (1967)
• Fender "Musical Instruments” Special Design 10” —this is a 1974 CTS AlNiCo driver 064121 137 7418
• Original 2 wire power cord, power supply, reverb tank and bag. 
• Handle, hardware and knobs original.
• Filter Caps original, Bias supply was rebuilt.

NB: The power transformer has a 1969 date code, and the waxy drippings on the speaker baffle are evidently from the original transformer that failed.  The output transformer, choke and pots all have 1967 date codes.   

The tubes are newer, replaced about 10 or 15 years ago, but the amp has had little use since. Here’s what’s in the amp now:
• 1 RCA 5U4 rectifier
• 2 Russian 6v6gt output tubes
• 2 Russian 12ax7/7025s
• 1 12AT7 reverb driver

Non-Original parts:
• A standby switch was added next to the outlet, behind back cover
• Low voltage rectifier rebuilt
• Several orange drops replaced, along with a few resistors
• Tolex doesn't look original, probably replaced by others.

The Front panel has some wear to it, where you would expect; around the input jacks, the knobs and just under the script logo. Some of the knobs are slightly deformed. Light weight, compact and clean, it plays well.
