Background Behind the Build

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. I chose this amp for a few main reasons:

• Clean-ish amp playable at very quiet levels
• tube reverb circuit
• Great vintage blackface sound out of a quiet amp

Design Process

I do all of my designing in eagle, so that made the design process of this amp quite difficult, as Eagle is not meant for this kind of PCB design. To see how I did this, along with what parts libraries I used, check out my blog post on this topic.

Part Sourcing

For this build, I ordered most of my parts off of one of 3 supply stores: Mouser, Amplified Parts, and Tube Depot. I will do a more in depth run down of the parts I used in my blog post, but here is a quick run down:

• Carbon Comp Resistors (like a vintage Fender)
• 716 series orange drop capacitors
• Sprague Drain capacitors
• Alpha pots

Information about/difficulties with the build

I had one major difficulty with noise on this build, but it was the same issue as on my Two Rock build. If you want to see my troubleshooting techniques, along with some gutshots of my amp, check out my blog post on this topic.

Final thoughts

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. For my elongated final thoughts and some pictures of the amp, check out my blog post on this topic.
