Can this amplifier be used as an audio amplifier?
Asked by Anonymous on February 13th, 2016.
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.
Can this MOD 102+ Version be ordered with the European (220-Voltage) power transformer?
Asked by Anonymous on November 20th, 2015.
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.
Is there a Hammond cage that fits the chassis?
Asked by Anonymous on November 28th, 2015.
Our SKU P-H1451-16 should be a compatible fit.
What is an ideal speaker (watts and/or size) for this amp?
Asked by Anonymous on February 12th, 2016.
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.
Can you tell how wide the chassis is without the handles?
Asked by Anonymous on February 24th, 2016.
The chassis is 10" in length without the handles.
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.
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.
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 19th, 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 30th, 2017.
Yes, do a search for K-MOD102-F. This is our foreign version of this kit.
Do you carry a higher end output transformer than the P-T31 that will work with the MOD 102+ amp?
Asked by Anonymous on December 1st, 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.
Can I add a reverb tank to this kit?
Asked by Anonymous on March 9th, 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.
Hello. Which transformer would I need for 240V AC in Australia?
Asked by Anonymous on September 25th, 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 February 1st, 2019.
Yes, it is safe to use a 16 Ohm speaker with this amp.
Is this amp good for bass?
Asked by hyperchuck on January 22nd, 2021.
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.
Can I install another input for guitar/mic?
Asked by Anonymous on June 4th, 2021.
It is very likely possible, but changes to the circuit or modifications to the kit would be done at the discretion of the builder.
