2. Wiring Diagram / Layout
Our beginner level kits such as the tweed champ and tweed deluxe include a manual. If you purchase a kit from Mojotone and do not receive these documents, you can obtain copies by emailing email@example.com or calling 800-927-6656. The Mojotone staff is available Monday through Friday from 8:30 a.m. to 5:00 p.m. EST unless otherwise closed.
Mojotone kits include the best quality parts that are available at the time of purchase. If a substitution is required, our team will use parts that are of equal quality to ensure the integrity of the kit build remains the same.
Building a fully functional amplifier kit is not an easy task. Before building a kit, one should have the ability to properly solder as well as read and understand a schematic and wiring diagram. While we do our very best to ensure all documentation is current, the included documentation is meant to serve as an overall guide to building the amplifier. Simply following the schematic and wiring diagram does not guarantee you will have a fully functional amplifier. In fact, post build troubleshooting is a common issue across all builds.
Our staff is available to assist with basic troubleshooting needs. There are plenty of online videos available that are helpful with most post build issues. Technical staff is available via email by sending a message to firstname.lastname@example.org. You may also call our sales team to discuss build problems, dial 800-927-6656 and press 1 for sales.
Building a tube amplifier takes time, dedication, resources and most importantly... Skills! The experience of building an amp can come with some frustration, the reward of completing the build is definitely well worth your time. Please review the wiring diagram, schematic and manual (if applicable) prior to making your purchase. Mojotone will not accept any returns on amplifier kits and/or parts that have been assembled, soldered or modified.
Ratings & Reviews
Great kit! Always wanted that iconic 70's-80's hard rock sound and this amp captures it. I initially decided on this kit as a platform to experiment with JCM/plexi mods but I decided to leave it alone. Throw a clean boost in front of it and it's perfect. I'm already using it as my main amp. It was a lot of fun to put together and I needed nothing other than a little extra wire. This build should not be for someone who has little or no experience though. You're going to need a rudimentary knowledge of basic electronics, tube amp design, circuit construction and a healthy respect for safety. You get a box of parts, a layout and schematic, the rest is up to you. I believe they have good tech support if you need it though.
