transformer in dynamic mics

[Dave-Morris]

I've just acquired an old (green in color) Altec-Lansing 686A mic

It works, but the cable insulation is falling off just in handling-

The original transformer was potted in what appears to be beeswax and then covered with a layer of tar (or it could be the remnants of the adhesive from the electrical tape which was wrapped around everything)...

I'm not sure I can get all the gunk off in order to get a clean (and electrically sound) solder joint- plus there's a conductor back to the XLR thats not used (although connected to a trasformer point) so i think this originally may have been a Hi-Z/Lo-Z mic with the 4 (or 5) pin XLR plugs

it has a really pretty gold diaphragm Grin

I do have a Sennheiser something and an Audix something that I could dismantle for a transformer... or if I knew more-or-less close to what kind of transformer to get I could just buy one- I found transformers used in old telephone handsets for the mic which might be a pretty good match?!?

I figure the mic will be good for blues harp or voice over for remakes of "War of the Worlds"...

Wow, sounds old. There are a few common liquid products that are designed to remove old tape and glue residue. They go by names like Goo Gone, Oops, and De-Solv-It. You can find them in the glue section of your local department or hardware stores. They work pretty good, but I don't know about the bees wax part. Maybe you could set it in the forest and wait for the bears to lick it clean. Cheesy

I understand that transformers are not that expensive. But that's about all I know about them.
