The MOD 102 is a great place to start for those interested in building their own tube amp. It is based on a classic American tube-circuit design combined with a British-style Class A output tube section. At low volume it produces a clean, chimey tone that moves into smooth overdrive at higher volumes. All parts are included along with a pre-drilled steel chassis, wire, and tubes (1 EL84 and 1 12AX7). Puts out at least 5 watts. The chassis layout is open for easy assembly using the clear, easy to follow instructions. You will need your own tools and solder.

Here is what people are saying about MOD 102 Guitar Amp Kit
"This was my first tube amp build and it was extremely easy and fun to do. I admit that I don't have enough experience with other amp kits to compare it to, but I cant imagine having a better starting point for tube amps, and the tone controls are a cool plus!" "Just the idea of this is awesome! Drive it with some P-90 dervish, dial to 10, strum chord, lean guitar against cabinet, walk across the room and have lunch while the noise self-perpetuates. Music to my ears!!!!" "Got the kit this week and finished it in about two days. Instructions and diagrams were excellent, would definitely recommend this kit for beginners. Fired up the amp for the first time and it worked perfectly. I am pretty impressed with the sound, has a nice tone and a lot more power than I would have expected."

13 year old Chase Walker decided to build a tube amplifier for his 8th grade science project. After researching the many amp options we chose the MOD 102 DIY Guitar Amplifier Kit.

It is a demonstration of step by step, the assembly of the kit 102. Good kit, good instructions, honest sound for the price.

Can the power transformer be wired to work with voltages besides 120V?
Do I need a speaker to hook this up to?
Could this be modified to use an EL34 in the power section instead of EL84?
Is this good for someone who doesn’t have any experience fixing or modding guitar amps?
Can a master volume be added in order to get distortion (high pre-amp gain) at low volume levels? If so, how?
Do you have wiring instructions for when using a 369EX power transformer?
Are the cold and hot legs on the bass, treble, and volume potentiometers interchangable as long as I stay consistent? I wired the backwards...
I've built this and love it. Is there a way to modify this so I can select the output ohm between 8 and 16? I realize a different transformer would be required plus some wiring changes. It would be ok if it was somewhat "hardwired" for one or the other, but I'm not intimidated with drilling holes for multiple output jacks.
Can I use different preamp tubes to change the gain, like your preamp pedal?
How / where could ! add an Effects Loop ?
is the chassis for this 10 x 6 x 2?
Do you have a schematic to build a 40W amp?
DO I need to scratch the paint off of the chassis at the grounding points or is making sure there is bare metal in the screw holes sufficient? I am worried that the screws are not in 100% contact with the chassis. I made an effort not to remove any metal at the screwhole sites. Thanks in advance Rob D
Hi, I have just completed a tubedepot 5F1 (Fender Champ clone). It was a load of fun and I would now like to take on your Mod 102 kit (I bought a Harley Benton Celstion Vintage 30 1x12 cabinet in anticipation...). My question is, is it possible to reconfigure your Mod 102 to less than 5w output? In my house even 5w is too loud to crank to distortion, so I'm trying to find a 3w or even 1w tube amp kit. Thanks Dave
Could this be modified to reduce the output wattage? either a knob for variable wattage or a switch with low, high wattage settings?
Can it be wired for 100 watts, rather than 5watts? Like for 2x12 speakers
Good afternoon, I just received my MOD 102 kit in the mail and am excited to start building. I have a question regarding the labels. Are they adhesive or am I supposed to cut out the pieces of paper in the instructions and glue them to the chassis? If adhesive, they were not included in my kit. Thanks
Are there any modifications that can be made to make this more suitable for bass?
Is there a source for better labels or a faceplate for this amp?
