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 additional “+” 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

It could be used as an audio amplifier but you would not get a lot of clean headroom before it breaks up. It's design is definitely for guitar.

You could adapt this for hi fi, but you would need to drop the gain in the preamp stage(s), by using several methods, and change some other components for better frequency response. True global NFB, and changing the slope of the gain stage would help, but then you will also need separate phono preamp(s), and another channel for MP3s, digital, or CD inputs, etc. It was designed as a guitar amp. I thought Antique Electronics did make a little hi fi amp kit, at one time. They also used to sell Dynaco parts & modification kits too. I think they still make one that eliminates the need for 7199 tubes.

The MOD 102+ kit comes standard with a 115/125 vac power transformer and can not be customized. However, the European transformer can be purchased separately and the kit can be modified to suit your needs.

Our SKU P-H1451-16 should be a compatible fit.

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.

The chassis is 10" in length without the handles.

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

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.

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

Yes, do a search for K-MOD102-F. This is our foreign version of this kit.

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.

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.

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

Yes, it is safe to use a 16 Ohm speaker with this amp.

Bass amps will traditionally be higher in wattage to allow for clean reproduction of low notes at reasonable volume levels. This amp may get into breakup earlier than anticipated when using it with a bass, but if that sounds ideal for you, this may be a great fit.

This is a great amp! It has great clean tone and reacts well to my pedals. I never crank the volume past about 9:00 (I have small kids at home), but at low volumes it sounds lovely. The kit was easy enough to build, and the instructions were appropriately detailed for a novice builder. The components seem to be decent enough quality. I notice the control labels recently received a refresh (shortly after I purchased mine, apparently); I hope they took the opportunity to improve the quality of the material used for the labels, as the vinyl-backed paper used before tends to degrade quickly with any rubbing or curling. Also, I had trouble getting the self-tapping screws for the chassis to self-tap; I had to use a tap bit on my drill to cut through the chassis sheet metal. I would also recommend printing the parts list in color to help with identification of the resistors (unless you have your color codes memorized), as the instructions I received were black and white. For the money, though, this is an excellent kit - fun and straightforward to build, with delightful results.

Nice little kit! Instructions are pretty clear and it's certainly not overly complicated to build. Having some amp repair/building experience helps, but I'd say even a beginner could buy this, build it, and be playing it within a day or so. Once built it sounded pretty good as well. Fun to swap tubes around, substituting the 12AX for a 12AT, AY, or others. The 'effect' changes on the pull switches are pretty subtle, so don't expect anything dramatic there. But, the amp makes a great platform for learning, and even 'expanding' from the original design. I've put an EIA connector in the back of mine so I don't have a cord sticking out. I put some tall 'feet' on it so it would clear a speaker box handle. And, the power transformer is suitable for adding a 6CA4 rectifier, which I plan to do in the future. I'll have to move the filter capacitor section around some to make clearance for the socket, but it's a 6 volt 9-pin rectifier, so will work perfectly in this amp. I might even 'upgrade' the output transformer....or play with some yellow jacket type adapters to try a different output tube. In all, a lot of fun to build, sounds great for what it is, and I'm very glad I made the purchase!! A 'GREAT' value!!!
