I have been commissioned to build a friend a Princeton Reverb. I can't for the life of me come to building any amp bone stock, so I am sure I will deviate from Fender's tried and true design - but not by much. My friend wishes that the amp be built into a Tweed 5E3 type 1x12 combo. I ordered one from Guitar Cabinets Direct for $286. It looks quite nice! Next I raid my stash of transformers. I have one with masking tape labeled "Deluxe Reverb". It carries the marker 40-16519. Seems like a Classictone? I found some info on it here: https://www.tubesandmore.com/products/transformer-fender-replacement-power-330-0-330-v-120-ma https://www.tubesandmore.com/sites/default/files/associated_files/p-tf41316_wiring.gif It appears a Deluxe Reverb PT is 10v hotter than a Princeton Reverb. It has higher current potential on the B+ and the 6.3 filament winding. I reckon it should work just fine, especially with JJ 6V6's that I tend to use. I selected this OT: https://www.amplifiedparts.com/products/transformer-hammond-output-replacement-fender | A Hammond P-T1750E. I bought an undrilled 5E3 aluminum chassis. I'll be working from Rob's fantastic PR schematic and layout: https://robrobinette.com/AA1164_Princeton_Reverb.htm I imagine I will have switchable NFB and possibly a tone stack lift. Other than that pretty standard. Away we go!
