Classic Tube Guitar Amplifier

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."
