For the Vibrolux portion of this build, the PCB build was fairly easy. I simply coppied the board layout off of the Fender schematic, which I have posted below.

Below is my EAGLE board design:

I also had to design a cap board and a bias board, which you will be able to see in my finished pictures of the amp.

The reverb design process was much more difficult. Because Dumble had a few reverb design circuits and almost none of them (that I could find) had reliable schematics, I had to draw my own schematics off of verified layouts. After I drew them, I compared them and found the differences between them.

‍

The main difference I was able to find was the NFB loops around the tubes in the Steel String Singers. In my final schematic, I added local NFB loop switch using a relay to determine wether or not there would be local NFB loops in the circuit. Here is my layout for the reverb unit.

During the PCB design process, I also had to build a relay board. I also had to account for a different, lower output power transformer that had a 5v tap.

Because i designed these PCBs, they are of course available for purchase! Let me know if you would like to purchase a PCB, or just get the .brd files so you can order them yourself.
