I would like to investigate un-potting my LX5's. I've done some research on the internet and was hoping someone in these forums could either tell me what the material is that was used to pot them or what I can do to un-pot them. ( I also searched these forums and did not find an answer.) It has also been suggested that I by-pass the LX5's.
About twenty years ago I replaced one of the LX5's and as part of the deal I had to hand in my old one. I assume it was going to be rebuilt so somehow these are being un-potted in a nondestructive way. Unfortunately the old shop is gone so I can't ask them what they do with the old ones.
If it is epoxy I've read that acetone might work on certain epoxy variants. Failing that you are into some very nasty chemicals like Nitric Acid or MEK. I imagine all theses chemical would strip the paint and other markings off the case which is something I want to avoid.
If is tar I assume something like varsol would eventually release the contents. Bee's wax would be ideal, warm water on the stove was suggested in these forums.
Has anyone un-potted an LX5 or other vintage JBL gear and could you share some detail on the steps you took?
