Just picked up a Frankenstein Head in pretty good condition. Started taking it apart to replace two prong power cord and noticed tag inside that says J695-PA. From reading a post on the forum it appears this is a K200 that would have been sold with a cabinet with Jensen speakers. My guess is that this was originally a PA head rather than a guitar head. Were there any major differences between guitar, bass and PA heads from Kustom? Can you convert a PA head into a Guitar head? Not a noob but I wasn't able to find previous discussion on this topic.

Welcome to the place...
Just my experience, these heads for the most part can be used for bass, guitar, vocals, PA', keyboards whatever you want to throw at them. They work. The speaker cabs you tie them up with is what will make the difference. Also for bass you wouldn't normally use a unit with effects, but I have a friend that uses trem and verb for some interesting effect.

These amps have a fairly flat frequency response. My daughter is using a "PA" head with a 2x12 cab with CTS bass speakers in it and it sounds great. I have a "PA" unit hooked up with keyboards running a 2x15 JB Lansing cab and it can call the cows home. I guess what I am trying to say is hook it up to a cab, plug in and enjoy. Oh do not put less than a 4 ohm total load on it if it is a frank. The 100 and 150 series amps are designed for a 8 ohm load and the 200 - 250 series amps for a 4 ohm load.

Other than that Enjoy

PS keep your input level below 1 volt especially on the older amps you can overload the first one or two transistors in the preamps with too hot of a signal. Changing out he two wire to a three wire grounded cord and removing the death cap is something I do as soon as I get a new one in.

Agree. All of the amps use the exact same circuitry regardless of the model name. The different models had different features and came with different speaker cabinets that made them more appropriate for use as a bass amp or a guitar amp or as a PA.

The PA heads had reverb only (no vibrato) and did not have High and Low (frequency) inputs.
