MHB Custom Fender Princeton Reverb Amp
Hand built custom Fender Princeton Reverb Amp by MHB
While inspired after my first amp build ever, a Fender Tweed Champ 5F1, I was simply hooked at building Fender amps based of of some of the most sought after amps ever made. My initial build was going to be either another tweed 5F3 or a deluxe reverb, but after playing a Princeton reverb at the local guitar shop in Annapolis Maryland, I knew exactly what my next build would be. As always my initial step was researching as much info as I could on the Princeton Reverb. I scoured the web for information, schematics, mods, etc… A list of website I found most useful are listed at the bottom of this post.
Everything in the amp itself is based on the stock Princeton Reverb AA1164 Circuit. I decide to upgrade the output transformer for increased watts and headroom for better usability in live situations. You can see the wiring layout doc I based this off of below. Overall I’m extremely happy with the OT and sound. It still breaks up after about 4-5 on the amp, but it is a considerable amount louder up to 4 compared to an original. The OT requires a different rectifier from the 5U4GB and uses a 5AR4 tube.
Looking back and in the future I would probably just buy a chassis, but for this amp I hand built the chassis based on original specs. I had a buddy bend the metal for me in the back of his truck and drilled all the holes and cut outs by hand. Man this was labor intensive! It almost took as long to make the chassis as it did to build the entire amp.
