This Princeton Reverb was built in 1969 and features the "drip-edge" aesthetics, indicating the transition era. A key feature of this era is the circuit, indicated on the tube chart as carrying over the Blackface AA764 circuit. This is a great value opportunity, since they have the same circuit as the more expensive mid-60's amps, but at a fraction of the price.
The amp is in good shape, with moderate wear mostly isolated to the bottom left side of the cabinet. There are some white stains and a bit of gaff tape on the bottom, likely due to a tolex issue. Fortunately, everything remains structurally sound, with no other concerns regarding the cabinet or tolex.
Internally, the power cord and electrolytic caps have been replaced. Otherwise, the preamp is completely original, with all of the factory resistors and coupling caps intact. The speaker has been swapped for a 2005 Jensen Alnico P12R, and the reverb tank is an OEM unit from the 1980s—which does a great job of preserving a vintage-style reverb sound!
