Vintage 1971 Fender Princeton tube guitar amplifier (silverface) in very good condition.  It puts out 12 watts RMS into an 8 ohm 10” speaker.  The amp has that crisp clean Fender sound that others have tried to emulate for decades.  The smaller silverface Fender amps (Champ, Vibro Champ, Princeton, Princeton Reverb and Deluxe Reverb) have almost the same circuitry as their much more expensive blackface (pre CBS/1967) counterparts.
There are no operational issues with this amp.  Everything works as it should.  The tubes include a 5U4GB for the rectifier, 6V6’s for the power, and 12AX7’s for the pre-amp and phase inverter/tremolo).  The silverface faceplate is in great shape with only a few minor scratches.  The grill cloth has no rips or tears.  The tolex has a few bumps and bruises along with some small red paint spots, but over-all for an amp that is over 37 years old it has held up extremely well. The speaker is the original Fender 10” speaker (no model # but it is likely an Oxford 10J4).  The tube chart is intact and is in great shape.  Get it while you can, these amps are skyrocketing in price.
