It took a couple of weeks of researching kits and amp types before I made a decision on what to build. I also considered whether or not I should build and wrap my own cabinet, but in the end I decided to spend more energy on getting the wiring right for my first project. Ted Weber's kits are affordable with a lot of options to customize the cabinet that they build for you. I chose the 6A20 Amp Kit, which is the Fender Deluxe Reverb circuit.
The AB763 is not a quick build and requires patience and a lot of wiring. If you're not sure of what you're getting yourself into, I'd recommend starting with a simple circuit like the Fender Tweed Champ. I want to thank Rob Robinette for all of the great information he has shared on his site. I wouldn't have undertaken this project alone without his site as resource. I want to emphasize that working on tube amps can be dangerous. Please work safely and reference multiple sources when starting a project like this.
Weber had a Memorial Day sale, and I ordered the 6A20 kit for $590 after tax.
