New - COMBO SUPER CHAMP Amp
We have taken the circuit of the Super Champ Head with all of the Class A Single -Ended Sweet Tone and put it into a custom stainless steel chassis with silkscreen lettering, added a custom power transformer, and build a cool new combo amp that ROCKS! This amp is available with a custom Mojotone 10" cabinet and Jensen speaker. The chassis is available as a kit or fully assembled. We also sell the whole amp assembled, tested and ready to go. This is the best small tube amp value available anywhere. This amp is 9 watts of sweet single ended tone with gain and volume and a sweet tone control. This is one dynamic amp with a low cost Jensen C10Q Speaker. We highly recommend it. It just blows away speakers costing three times as much.
The kit version of this amp features a stainless steel combo style chassis that is drilled and silkscreened for easy assembly. We supply an all new HTML Assembly Manual on CD with closeup photographs of every step and as always, we supply free email support. The power transformer is a custom wound high quality transformer with a tapped 6.3 volt heater supply. We have switched over to the Belton high quality sockets for this kit and all of our kits. These are much better than the Russian "tube base crushers". Kits are in stock now and ready to ship.

The large holes are done by us - Wire is included - quality solid core wire - you will not find solid core wire locally - and you get a 65 page step by step manual and FREE email support. - You don't have to download the schematic and plans - you get a full manual. All Hardware to mount and build the amp. No trip to Home depot looking for screws and nuts - they are included.
This Amp has a Dynamite Sound!! Builders have had great comments about the Tone from this inexpensive little amp. The book really holds your hand while building. Anyone with minimal skills can build this amp sucessfully. No prior electronics experience is necessary. Comes with an assembly book - and wiring board - no ugly - messy and noisy point to to point hand wiring. Tested layout!

Here are some nice comments and photos from recent "Champ Head" Builders
William Jahnkow's Very Nice Champ Head in a Homebuilt Enclosure
Thanks - William for finding the schematic error!
Mark Austin's nice Champ Head Project
Here are some pics of my Champ head, feel free to use any of this in your marketing. I really enjoyed building the champ head. Your directions are very good and it was a very manageable project. It's a great way to get a better understanding of amplifiers, too. This circuit puts out fantastic tone. In fact, now I realize how much my original '64 Vibro Champ is suffering from quite a few tired parts and even design shortcomings. A handmade, point to point amp simply puts out better sound than a 40 year old amp with a 40 year old transformer, tired caps, worn speaker, etc. I like old amps as much as the next guy, but stabilizing one of these beasts to get the hum down and the tone back is neither cheap nor easy. If money is a consideration, your champ head is really a no-brainer. Thanks for the kit! Mark, Austin, TX
Pictures of Mark's "Champ Head"
The two beautiful images below are Ray Soave's "Champ Head" in his own custom enclosure. This was Rays first amp project!!
Some of Ray's comment are "I've attached a couple of photos of my Champ. First amp build; first cabinet
build (a friend helped me with the finger joints). I love it. It sounds
great in the living room (my wife thinks it's cute) with a lap steel and a
Deluxe Memory Man."
Here is a very nice MINI Amp built from our parts kit by Charles Osthelder. Charles reports that the amp sounds great and he uses a 4 x 12 speaker cabinet!
Here are some of Charles's comments:
"This is a wonderful little tone machine! I can wait to record with it. It screams with the Les Paul and sounds very nice with my Strat. Best of all, it doesn't leave my ears ringing!"
"It's not like I've got poor amps to compare to- Marshall Super Lead 100 (1979 vintage) Fender Tweed Deluxe-like DuKanes that I refurbished, a Champ and several homebrew miniamps based on LM386 IC's. My STF Miniamp is the new Number 1 in my studio!"
