Mojotone’s Tweed Champ Style Amp Kit is based on the beloved 5 watt amp from the 1950s. These amps were perfect for recording and were featured on a wide array of recordings from Joe Walsh’s “Rocky Mountain Way” all the way to Derek & the Dominos’ “Layla.” Modeled after the historic Class-A 6V6 platform, this amp delivers warm tones that are harmonically rich and have a beautiful low volume crunch.

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 tech@mojotone.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 tech@mojotone.com. 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.

I purchased this kit without the cabinet or speaker. The amp is a pretty straight forward build and merits the 1 out of 5 build difficulty rating. The 4 hour build time is pretty close for someone with a little experience but might be a bit shy for a first timer. I built my own cabinet and paired the Champ with a 20 watt 10" speaker.



The amp puts out studio quality sound and belies its 5 watt rating. As mentioned in another review, it mics up really well. It also takes pedals really well.



Plus, the folks at Mojotone are always great at helping on any technical questions.

This is the 2nd amp I built from a Mojotone kit, the 1st being a 5E3 Deluxe. Both were so much fun to put together. Their instructions are spot on, and the quality of the components are top notch. When you're done, you have an amp that's worth twice the cost of the kit, had you purchased it from Fender. I actually found the Deluxe build easier..it had more parts, but with my large hands & long fingers, the smaller chassis on the Champ made it a bit more difficult for me to work inside. These guys are the best...if you have any issues, just email or call them & they'll fix it. Thanks dudes, Cheers to you.

Because I'm new to this whole amp kit thing I took my time but it still only took me about 6 or 7 hours and sounds great. thanks to the staff at Mojotone who answered questions very quickly. Great little kit, looking forward to the next one.

This kit was so much fun to build, I spent a lot more than 6 hours trying to make it look perfect. I didn't want the build to end. I added some NOS RCA tubes, and a 1/4" switchcraft plug and jack instead of the RCA, so I can profile it with a Kemper, and swap speakers in the future. The 1/4" jack requires no extra drilling, it fits in the existing RCA hole.



There really aren't words to describe just how good the tone is. Playing this amp instantly reminded me of all the greats who've used the 5F1 in the past, it sounds exactly like all those records.



Adding a looper and playing lead/scales over a rhythm loop, sounds incredible, the bell-like overtones and dynamics in the way the multiple parts interact, are thrilling. I love this amp!

Very glad to see that Mojotone came out with their own build manual and they now have a method of mounting the board as opposed to letting it hang by the wires. I now feel as though I can recommend this kit to others.

Greetings, I've been building Mojotone amps for a few years and I'm intrigued with all of the kits. They can been modified to whatever sound/tone you wish to achieve. The Tweed Champ is one of my favorites. You can build it with an output transformer that has multiple taps. Plus you can build it with a 10" speaker. The wood shop builds all my cabs and baffle boards. They do a terrific job with custom requests.

I build both the stock kit which is perfectly matched to the traditional Tweed Champ. I've also explored with military grade resistors and wiring to eliminate virtually all ground loop noise. I also use some grounding tricks to eliminate feedback. Aluminum chassis help greatly. I boost the sound with a 30 watt 10" speaker. This allows me to play gigs in a small room with an awesome sound. Mic it and send it through the P A

and you've got the sound of a big Tweed amp. It's hard to believe this Little Giant has so much capability. I use this amp for practice as well as for gigs. It's easy to carry around and people wonder how you get such a huge sound from such a small amp. I also like taking it to gigs and setting it up with an A+B pedal so I can solo through the Champ. It's a great crowd pleaser. I've found that no matter what amp you decide to build

Mojotone amp kits are the answer to all your craving sound needs. I don't go by the time it takes to build an amp. I'm doing so many other extra things I just want to get it right the first time. I only use silver solder and silver plated military grade wire. Any copper wire is silver plated before installation. I just don't like the way copper oxidizes and lead solder deteriorates. I taught jewelry for years and use my knowledge base to improve what I'm able to control.

The layouts provided by Mojotone are extremely accurate. Plus the pictures they provide add so much info it's hard not to get it right. I love every amp I've built. they mostly have gone to students that once they hear that magic sound they can't resist wanting the amp. The Tweed Champ is an excellent first build. It will lead you into exploring the riches waiting at your finger tips. ROCK ON!!!

This was a lot of fun and I got a great amp out of it. I would suggest using the online instructions as they were better than the ones that my amp shipped with and have somewhat simpler grounding points for some components and gives you a better idea of how long to cut your leads. I used the included instructions and my amp still works fine. All the parts came well organized in a compartmentalized plastic container which made it easy to find each component. I did have one extra capacitor and was missing one resistor. This is my first traditional tube amp and it sounds great. I turn it up to 6.5 and just leave it there. It sound great for blues. The only issue the amp had was my fault for putting the rectifier tube in wrong. The fuse saved it, meaning it did its job. I'm a mechanical Engineer with a lot of soldering experience, I used an adjustable soldering station, Weller wes51, I don't think it would be fun to do this with a cheap straight plug in style iron as some of the components are quite large. If you take your time and check your work as you go you should end up with a pretty nice piece of kit in the end.

I built this kit about four years ago. This thing is a monster. Terrific clean tones at lower volumes and unparallelled overdriven tones just before max. My go to amp for recording. Trust me, tinkerers. Leave the stock 8" speaker in there! I tried others, and put it the American Vintage back in. Parts are top notch. I went stock, except I switched the orange drops for blue sozos, and used NOS tubes. Great kit. Boutique quality at an extremely affordable price!

SOUNDS FANTASTIC. Love this amp. Not 5 stars because manual could be more clear. Some re-dos for me- not a beginner. Drill eyelet board AFTER adding components? NO! Had to clip a cap lead and resolder with extending jumper in order to access nut attaching board to chassis. Learned/prevented pitfalls of wiring mistakes from "D-Lab" youtubes.(like keeping leads trim and neat between pre-amp and output sections) Some wire not SPECIFICALLY MENTIONED, but it IS ALL SHOWN in the diagrams. Missing-blk + wht wire for tube heaters-only 15"for spkrs included. 10-12hrs for me- I do take my time and get it perfect and solid. Great learning experience!

How to streamline the process

by Robert -

First off-great kit. High quality. Fired up great and sounds wonderful. Having said that...

Download the instructions from other amp kit manufacturers. The mojo instructions are thorough and they did the trick, but the order of operations was weird. There were a couple of times, following the instructions that made my life harder. Example: they had me install the power cord after I installed basically everything that could be in the way of me doing it. It was waaaaay harder than it had to be. Other kit instructions had you install it first and tape it out of the way. Likewise with the turret board. Other kits had you put it in before the pots and tube sockets....would have been easier.

Like I said. The instructions were thorough. I'm sure the other manufacturers are lacking in some way too. I'm just saying to read as much material as possible. Sf1 circuits differ little.
