Disclaimer: Some of the parts contained in this kit are subject to availability.

Mojotone reserves the right to change or substitute any and all of the parts contained in this amplifier kit without advertisement or notification to the buyer. Part substitutions made by Mojotone are guaranteed not to affect the integrity or operation of your amplifier kit. Time estimates listed are from start to finish. If you are new to tube amplifiers, additional time may need to be factored.

When purchasing a kit from Mojotone, you will receive the following documentation.

1. Schematic

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 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 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.

A great kit. Nice cabinet too.

by anonymous

I'm glad Mojo offers this kit. It's probably the ideal small Fender amp. We all love the tweed Deluxe but this design solves all the complaints against it - no flub, no fizzy overdrive, tighter response, controls that work like normal and are not interactive.

That said, it is a stiffer, dryer and more refined sound as a result. It's not a better amp than the 5E3. It's just, from a design standpoint, very well executed. The sound is very woody, midrangey, and warm. Depending on how you set it up, it can have some good headroom, or it can break up at relatively low volume. But it does have cleans - as much as any Brownface amp.

And it is true that this thing has gain in spades. When you get to 8 you have reached what most Fenders get to, but turn it up past there and you get even more saturation and distortion.

The Mojo kit is high quality. All parts are there. The supplied speaker is actually a good match for the amp if you want an authentic vintage sound.

You may have to fabricate a fiberboard insulation for the pilot light, as were present on the originals, to keep it from grounding out on chassis. But all else is pretty straightforward. I do think Mojo should supply this part.

A great kit. Nice cabinet too. Build is fairly straightforward but it's about as complex as a tweed Bassman.

I'd recommend this amp kit to those who want to hear something different. It's also extremely tweakable - a cathode bias switch, a Negative Feedback switch, you could be in tweed Deluxe territory pretty fast.

the finished amp sounds great

by anonymous

I built one of these back in June--the finished amp sounds great, as you would hope, and the build was pretty straightforward. I did, however, experience some issues with the kit--the chassis was missing holes for the bias board and filter cap board and the power cord hole was too small to accommodate the strain relief attachment--luckily I have a drill press, but I could see this being a pretty serious issue for folks who don't have the appropriate tools. At the time I did my build, the instructions showed 4 16uf filter caps, while one of the provided caps was 8uf--luckily the schematic indicated the correct values/locations, and I see that this has now been fixed.

There are issues I wish Mojotone would address for all of these kits, most of which have to do with sticking with the 60-year-old specs--for instance, more modern power supply wiring (for the safest connection, you should be wiring the AC cord black to one fuse terminal, the other fuse terminal to one side of the power switch, the other side of the power switch to the black power transformer primary, and directly connecting the AC cord white and power transformer white leads to each other, not to mention completely ditching the "death cap" ground switch (which is a relic of 1950's/60's non-grounded power supplies and is unsafe if wired in per the original Fender layouts). Additionally, I find that the bias resistor values have been incorrect for most kits I've purchased here--if you're learning how to build amps, you should definitely be learning how to calculate and achieve a correct bias on a fixed bias amp like the 6G3. It seems like Mojotone just took the original spec at face value and used the same bias resistor, when modern wall power and other factors generally result in higher voltage, and, consequently, a bias that's too hot and likely to exceed your power tubes' maximum plate dissipation. It would be nice if they built and properly biased the amp and used THAT bias resistor value instead of the outdated one. Finally, the carbon comp resistors are "old-timey" and all, but I'd prefer not to have unnecessary hiss in my amp--I recommend carbon film for a lower-noise alternative, and metal film for the 68k and 1m input resistors.
