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.

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
Just got my new offset kit in today! Thanks for the super fast service Mojo! The grill cloth on this offset head shell looks so cool, can't wait to show it off to my bandmates.
As the title states OMFG!!! Just wrapped it up last night and was playing it till 2 in the morning!!! Needed to work out a couple of issues. Who knew that OT primary leads phase is an issue, I do now. That and bumped up the bias range resistor and then magic!! Just killer tones till 2 ;0)
Not my first Mojotone kit nor will it be my last. Saving my ducats for a NC3015 kit. The long and short of it is the kit was well worth the time and money as the results are priceless.
