The MOD102+ expands on the same all analog vacuum tube classic American circuit design combined with a British style Class A output section as the Original MOD102 with some much added special “+” features. These special features include a three position progressive toggle switch for off-standby-power and additional push-pull functionality for each control - pull out the bass control knob for “mid boost”, pull out the treble control knob for “bright”, pull out the volume control knob for “turbo”. These new features and a JJ ECC803-S (a long plate 12AX7 known for its complex mid range tones) allow for a wider variety of tones and extra control for the user.

MOD 102+ Guitar Amp Kit Features:

  • All Tube Design (solid-state diodes used only for full-wave rectification)
  • 8W output power into 8 Ω
  • 1 channel
  • Vintage channel controls with push-pull functionality: bass (+mid-boost), treble (+bright) and volume (+turbo)
  • Vintage pilot lamp and screw-on jewel cover for power-on indication
  • Output Impedance: 8 Ω
  • Tubes included: one ECC803 (JJ Electronic brand preamp tube), one EL84 (JJ Electronic brand power tube)
  • Hammond Mfg 269EX power transformer and P-T31 single ended output transformer.
  • Cathode biased class A power tube operation (no bias adjustment needed).
  • Point to point hand wiring using terminal strips
  • Carbon film resistors
  • Metalized polyester coupling caps
  • Pre-punched steel chassis
  • Assembled Kit Weight: 5.55 lbs.

This amp puts out a max 8 watts output with an 8 ohm load. I'd probably suggest either a Jensen C8R or C10R if you prefer a 10" speaker. A 12" speaker such as a C12R can be used as well. You can visit Jensentone.com to check out sound samples.

you suggest C10R or C12R, but what wattage?

The C10R and C12R are both 25 watt speakers.

I've built two of these amps and a third I modded a bit. They sound great through 12" speakers. Put it through a 4x12 if you want. It sounds huge through 12's.

In regards to speaker wattage, you can go up in wattage but you do not want to go down. An 80-90W speaker will work as long as the ohms match. Since this is an 8 watt amp, it is not going to, "push" you speaker to its full potential and break it up. Some people like speaker breakup and some people don't.

They sound great through my Egnater cabs. I have two 80 watt Celestion Elite speakers that I run it through and it sounds great.

You can try either the P-T125CSE or P-T125DSE. The footprint will be different as these are larger transformers and you will have to drill at least one extra hole.

I just built a 102+ with a Classic Tone 40-18031 with 4-8-16 0hm taps with a rotary switch and dual jacks. Adds a lot of versatility and the tonal difference is huge.

There is not a cage that will directly work with this kit at this time.

An effects loops could be added to the circuit though any modifications would be at the builder's discretion as we do not have instructions for this mod.

Unfortunately we wouldn't have specific dimensions for a cab for these speakers. They are used in a variety of sealed and open back configurations and it would the builder's decision based on their needs. In terms of the series/parallel wiring setup you would use the wiring scheme that best fits the output impedance of the amplifier and based on your speaker impedance.

This amp is capable of providing 8W of output power.

Since this is an 8w amp at 8ohms, an 8ohm P10R should work just fine and sound fantastic.

It attached to the top of the chassis flush. That way there is no obstruction to the controls.

You will want to order this kit and this power transformer: P-T369EX. The footprint is different and you will have to re-arrange it on the chassis.

This would be possible and at the discretion of the builder. We would not be able to offer and support on how to achieve this mod.

Not without modification and that would be at the discretion of the builder. We do offer a reverb tank kit called The Wave. Do a search for: K-MOD103.

We do not offer this kit with a 220V transformer but we can special order this transformer for you: https://www.amplifiedparts.com/products/transformer-hammond-power-190-0-190-v-75-ma. Please note that this transformer will not fit the footprint of the chassis and you will need to drill a hole or two to make it fit.

The P-T369EX should work electronically, but may have a different footprint. Modifications to the chassis may be necessary for installation. https://www.amplifiedparts.com/products/transformer-hammond-power-190-0-190-v-75-ma

This is a great kit. I wanted to build a small amp so i started researching schematics online.
Then i found this kit. All the leg work has been done as well as step by step instructions.
I just started it so i can’t comment on tone,
but the ease and design of the kit is excellent.
Full parts list, schematic and instructions include.
It gives you a proven simple platform to start with and you can add your own modifications if you wish. Thanks MOD

I just finished this amp build and it sounds fantastic! I also just finished a Marshall 18 Watt clone and I have to say that the MOD102+ holds its own very nicely alongside the Marshall. In fact, I will probably use the MOD102+ for recording because it sounds amazing at lower volumes (the Marshall is loud AF). Honestly, if I were only going to build one of them today, it would be the MOD. I'm blown away by the tone! Great kit with excellent instructions. Great bang for the buck. The parts all seem to be top quality. I love the old style cloth solid core wire, too. I find it much easier to work with than modern stranded wire. The labels are a bit lame but I covered them with packing tape as suggested before cutting them out and they look fine. If you're thinking about building an amp, build this one.
