The Mod® Electronics 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.

Hi, this will only work with an 8ohm load. If you have two speakers that are 4ohm's each and you wired them in series, you would get an total load of 8ohms.

Hi, P-T125J will work for this kit. You will have to order it separately. It will change the sound slightly as this kit is designed for 5k and P-T125J is 4k. Also, any mods you do to this kit are at your own discretion.

We recommend P-T125J. This kit was designed around 5k so there is a slight difference since the P-T125J is 4k.

You would have to replace the stock transformer P-T31 with the P-T125CSE.

We do not offer this kit without the tubes at this time.

While it is possible, it would require one to design a seperate circuit for the reverb. We do not have schematics to add a reverb circuit to this amp, but we do offer a stand alone reverb kit that you can use in conjunction with this amp. https://www.tubesandmore.com/products/effects-kit-mod-kits-wave-spring-reverb

The 10" x 6" dimensions listed above are the size of the chassis without handles.

Purchased this kit from Antique Electronic Supply in for my 1st amp build. Instructions were clear, with no confusing or ambiguous steps. Layout diagrams were very helpful, but I recommend following the written step-by-step instructions when assembling. Assembly and soldering was easy. I found only one mistake (my fault) when I double-checked my work, easy fix. Checked all the VDC voltages at the given test points--measured less than 3% variance. Fired up the amp and very pleased with the sound; very! Nice breakup. I look forward to modifying the circuit in the future. Will do business with Antique Electronic Supply again.

I give the kit 5 stars and mine sounds great! I assembled it in around 8 hours and found no errors in the instructions, which were clear. I agree with the reviewer who griped about the labels, which are 1 star. Everything else is fine and it is obvious that a great deal of thought went into component selection. Mine worked the first time I tried it!

My first amp build!! Sounds great!! Just follow the easy instructions and it will work. I have little electronic skills, but it works and would recommend this to anyone wanting a hand wired amp. I built mine in about 14 hrs.

Good little kit. I built it in one evening, pretty easy build. I like the sound of the finished amp, nice and chimey, with a mild overdrive up until its close to cranked, where it gets pretty raunchy. It is very easy to hear the differences in various preamp tubes when swapping them, one of My favorite things about the amp.

This makes for a nice little practice amp. I have it running into a 16 ohm Jensen MOD 10 with a paralleled 16 ohm resistor. This setup is a little too loud for apartment use, although I can run the volume high enough to get a little dirt going so it should work out fine.

This is a good kit if You want to work on point to point wiring and soldering skills. The included instructions are pretty thorough, of course it helps to keep referring to the schematic as You work.

Overall I like the kit and amp. I have a few ideas for mods, which should be pretty easy given the nature of the thing.

Fast shipping to B.C., Canada. Built it in about 8 hours with no real problems. Works as expected. Good, clear instructions.
