This Princeton Reverb was built in early 1968, and features the "drip-edge" aluminum trim around the front baffle. In addition to this, the earliest transition era amps feature vertical black lines on the front silver panel, indicating a very rare and distinct example. Something that doesn't get mentioned much is the use of BC&T transformers for late '67, early '68 Princeton's - which translates to a bit more "edge" to the sound, displaying itself in an excellent way when driven to breakup. The reverb transformer has been changed, which goes unnoticed in terms of sound quality.

This amp has a changed power cord, electrolytic caps, along with most of the original coupling caps (one original "swedish fish" still remains). The reverb cables have been changed, but the original tank is still present. Also the V1 plate resistors changed out for modern carbon comp equivalents. A resistor was changed in the tremolo circuit as well, but otherwise the circuit has remained original. Despite a couple of changes internally this amp retains an authentic blackface sound, having kept the identical AA764 circuit as the previous mid-60's amps.
