Mr Freddy

Thanks for the reply! I actually resolved this issue with a lot of help from around the world. I traced the original transformer that Gibson used on its signature models, the precursor to the Epi JC. This was a UTC 0-1. The company stopped producing them in the late 60s, and later signature models used a transformer that looks exactly like the JC. I imagine they just had another company use the specs but the housing is very different from the original. Getting lucky on eBay, I sourced the original transformer and after some trial and error introduced it into the circuit. So my JC now has a 60s era transformer driving the circuit, it’s one of a kind! It was an expensive fix.. AND after months of bothering them, epi gave me the info I needed and I sourced the modern part (AFTER I fixed the bass). So I have a spare now. Part was cheap. No regrets though, it was a fun adventure, and I learned a ton of info that only a handful of people in the world care about.

Good evening, I am trolling every forum that may be able to help. I have a Jack Casady bass, which has similar wiring to the low impedance Les Paul signature bass. The circuit uses a transformer to boost the signal, and the part is covered in epoxy. The output wire broke at the epoxy. I dug a bit but could not find the lead. I have someone trying to extract the part to fix or fabricate, but the chance of success is low. Epiphone will not talk to me about the part, says I must use authorized dealers. Quite literally every major dealer in the country says they cannot help me. Does anyone here know where or how I can get a replacement for this part (the bass is still in production as far as I know)? Or even any info on the part, such as does it correspond to the Gibson onboard transistors for similar low impedance models? Kind of stuck. thanks for any help you can offer!

Good evening, I have a problem somebody here may be able to help with. I don’t own one of the classic low impedance Gibson’s, although I have always lusted after the Les Paul recording and triumph basses. I do own an epi Jack Casady. The internal transformer is the issue, it is potted with epoxy and my output wire broke at the epoxy. Right now it is out to someone who may be able to repair it but says 50/50. Epiphone says they can’t help, only authorized dealers deal with parts and repairs. Every authorized dealer in the country says they cannot help me. So my options are getting limited. my questions are: 1. Does anyone know if the JC transformer is the same or similar to the classic Gibson models? 2. Does anyone know where to get a replacement part, either new or fabricated? 3. Does anyone have technical info on this transformer to help with fabrication if I cannot get one through the company that manufactures the part? Thanks in advance for any leads or insights you may have, this has been quite frustrating! -Mark
