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
Build this Kit!!
by Richard F. -
First off.. the web page wouldn't allow me to give a 5 star rating, which I would for the British Style 45W Amplifier Kit. This was a top notch kit from all aspects and properly built will give you an awesome clone of JTM 45. All the parts included in the kit are top notch and lead to a great sounding amp when finished. I was skeptical on the turret board with the holes, but it worked out great and I ended up routing wires through the holes to provide strain relief. Also found the octal tube retainers a little funky and changed the out for Belton tube clamps.. much better. If you're looking to add British clone to your arsenal, I HIGHLY RECOMMEND building this kit. It's simply outstanding..
Last, I've also tried kits from other vendors to see if they compare. Don't go there. Stay with Mojotone, every kit I've built over the years has been excellent!
