As a basis for this amp, I decided to use a Fender Vibro Champ, a 5-6 watt amplifier that acts much like my previous Deluxe Reverb Build. To try and spice this build up, I decided to add a Fender two tube reverb circuit to this build, as well as create my own PCB for the amp. This is one of my main reasons for wanting to build this amp as opposed to many other amps on the market. I also wanted to add my own sharkbomb touch on this amp, and that is where the fender two tube reverb circuit comes in. This amp is extremely quiet (meaning it is playable at bedroom levels) and still gets the wonderful tube breakup sound that one would get from a vintage fender. This amp acts much like my fender Deluxe Reverb amp, just at quieter levels.
To create the board I used Eagle, my PCB cad program of choice. Eagle isn't really meant for creating eyelet boards, so I kinda had to work around the limitations within my program. To do this, I made the base PCB the size I wanted it and created the schematic to mimic the layout and added some large eyelet-style holes that an eyelet/turret can fit into. I then put this all on a 2mm thick board with giant traces to cary the signal and high voltage.
For this build, I ordered most of my parts off of one of 3 supply stores: Mouser, Amplified Parts, and Tube Depot. Because Mojotone knows a lot about these amps, I kinda coppied their bill of materials from the Deluxe Reverb, making the appropriate changes where needed. This means for the tonal section, I used Carbon Comp resistors, while for the power section I used carbon film resistors. I also used 716 series capacitors, a Mojotone cap can, TAD tubes, and a Webber Michigan Speaker. For my cabinet, I decided to get a Guitar Cabinets Direct cabinet, because I was very happy with how my other one sounds and for a fully customizable cabinet, they are not too too expensive. One thing I did not like about this cabinet is that it didn't have pre-drilled holes in it, so it was quite difficult to line up where to drill the chasis mount holes. Other than that, I am very pleased with my cabinet.
This build was super clean in my opinion, and I think that is because of all of the under board wiring done with traces on the PCB. The amp came together fairly quickly; it didn't take me too long to get through the build. As I mentioned on my main post, I had one major difficulty regarding noise in the amp. I used the same grounding technique I used in my Two Rock build.
Super fun build. Taught me a lot about PCB design practices, and furthered me on my journey to get better at troubleshooting. Super light amp, and very quiet, meaning I can play it and make it overdrive at the same level where my Deluxe is just turning on. While this amp is still pretty loud, this is less of a take-out amp and more of a bedroom/recording amp just because of how loud it is.
