Some help with a 1974 Gibson Les Paul Signature (Low impedance pickups)
Hello everyone, new guy here and I hope you all have a great New Years! I could use a bit of help please with repairing an old Gibson Les Paul Signature (The 70's thinline ones). Apologies if this is the wrong section in the forum; I had a look through everything and I thought this would be the best place to post.
So, it seems that about 30 years ago someone decided that this guitars original electronics were not what they wanted and changed them to a typical Les Paul style configuration. If you're familiar with these instruments then you'll know that they are equipped with low-impedance pickups and I'd imagine that's why it hasn't worked since. Both the pickups are original, working and read 25-26 ohms so that's good news but unfortunately the rest of the original electronics are long-gone. After looking over the schematic I can tackle the wiring and replace/substitute most parts but I must admit that making the small transformer is beyond me. I'm aware that as a last resort I can still use a little line matching transformer to get sound but it would be nice to actually have the three position 'level control' to change the output impedance as well. :)
Can anyone make something like this or point me towards someone who can please? I've given up on finding the original part (number: 70-478) its like looking for hen's teeth. Epiphone did a re-issue a while back and the Jack Casady bass still uses the 50-250-500 level control if anyone has Casady electronics they'd be willing to part with. Here's some pictures of the original part:
Thank you for any assistance and have a great 2019 :cool: -Kev
