Recommendations for a speaker. I've purchased the kit, and would like to build it into a combo.
Asked by Anonymous on October 3rd, 2015.
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.
Is a 80w-90w 1x12 cab ok for this or do I really have to go for 25w speakers? How will it affects the sound?
Asked by Anonymous on November 22nd, 2016.
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.
Do you carry a higher end output transformer than the P-T31 that will work with the MOD 102+ amp?
Asked by mgb3333 on November 29th, 2017.
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.
Is there a cage made for this one like there is the MOD 101?
Asked by Anonymous on September 7th, 2015.
There is not a cage that will directly work with this kit at this time.
Can I order the enclosure with an IEC connection?
Asked by Anonymous on September 8th, 2015.
This amp is currently available only as a kit with no chassis customization options. We do offer IEC connectors for future modifications.
What is the difficulty level in constructing this amp? I've never constructed any electrical components before. Is it doable for a beginner?
Asked by Anonymous on September 10th, 2015.
The Mod 102+ kit is listed as having a difficulty level suited for the experienced builder.There are detailed instructions included but if you desire a more beginner focused project, visit modkitsdiy.com to see our assortment of kits designed for all levels of experience.
Is it possible to add an effects loop, to this amp?
Asked by Anonymous on November 22nd, 2015.
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.
you suggest C10R or C12R speakers for this built,but what wattage????
Asked by Francois Poirier on December 30th, 2015.
The C10R and C12R are both 25 watt speakers.
hello im planning on using a c10r speaker to build my own speaker cabinet.my question is ,do you have any info on dimensions for the cabinet? eighther sealed or ported cabinet? and also would it be good to use 2 of those c10r speakers...in series or parallel? thank you very much for your answer.
Asked by Francois Poirier on January 3rd, 2016.
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.
How watts RMS is the amp output?
Asked by Anonymous on February 11th, 2016.
This amp is capable of providing 8W of output power.
How about using a Jensen P10R Vintage Alnico 8Ω speaker? Any reason not to use one? Thanks.
Asked by Anonymous on November 11th, 2016.
Since this is an 8w amp at 8ohms, an 8ohm P10R should work just fine and sound fantastic.
How would the chassis cage mentioned above work....picture only shows one side but what about access to the controls etc...
Asked by Anonymous on February 24th, 2017.
It attached to the top of the chassis flush. That way there is no obstruction to the controls.
Can you flip it over and build a little combo out of it?
Asked by Anonymous on July 18th, 2017.
Yes, some people have mounted this as a combo.
Can I get this kit with the Hammond 369EX power transformer to suit foreign (Australia) mains power (240v)?
Asked by Anonymous on August 29th, 2017.
Yes, do a search for K-MOD102-F. This is our foreign version of this kit.
I really want to get the '+' options with the 'mid-boost', 'bright' and 'turbo'- I don't think the K-MOD102-F kit comes with these options.
Asked by Anonymous on September 13th, 2017.
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.
Is it possible to install a circuit or relays in order to turn on/off the Mid, Bright and Turbo functions on the amplifier via a foot switch?
Asked by Anonymous on December 25th, 2017.
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.
Can I add a reverb tank to this kit?
Asked by Anonymous on March 8th, 2018.
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.
It is a device that supports 220V in the Europan electricity network ?
Asked by Anonymous on August 10th, 2018.
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.
Hello. Which transformer would I need for 240V AC in Australia?
Asked by Anonymous on September 22nd, 2018.
The P-T369EX should work electronically, but may have a different footprint. Modifications to the chassis may be necessary for installation.
Would it work with a 16ohm speaker (of course with overall lower power output)? I have a cab and wanted a small head like this to use it along with my cab
Asked by Anonymous on January 17th, 2019.
Yes, it is safe to use a 16 Ohm speaker with this amp.
Where are the "Parts List Drawings" and "Assembly Drawings" the build manual refers to at the bottom of page 2? I do not see them with the other build docs.
Asked by danjbeckett on April 6th, 2019.
You can view those on the MOD Kits DIY website: https://www.modkitsdiy.com/kit/mod-102-guitar-amp-kit-0
What does the Turbo switch do? Is it for gain?
Asked by Anonymous on November 22nd, 2019.
Yes, it is essentially a boost to allow for more drive and compression.
I see it is only has one 8 ohm output.
If I expanded from 1x12 8 Ohm speaker to a 2x12 8 ohm speaker would it be better (safer for the amp) to wire in series or parallel to have 4 or 16 ohms? Or can I combine an 8ohm and 4 ohm speake in series to split the difference at 12ohms safely?
Or is there a mod of the mod kit that will let me change the ohms output?
Asked by Prudhom on February 10th, 2020.
For optimum performance, you would want to run a 2x12 cab with two 16 Ohm speakers in parallel or with two 4 Ohm speakers in series. If this simply isn't an option, we suggest wiring two 8 Ohm speakers in series to get a 16 Ohm rating.
A couple of questions above realted to Mod102+ indicate that the amp will run on 16 ohm load, even though it's rating of 8 watts is into 8 ohm load. Similar question on speaker load for the regular Mod102 says that to use 16 ohm load you need to change the transformer. Why the discrepancy here? I get why 4 ohm should not be used, but I would expect that either amp could take 16ohm with the expected output redeuction.
Asked by Anonymous on February 14th, 2020.
For optimum performance, we recommend using an 8 Ohm load with this kit.
