mag head for GI decks
I picked up a meissner phonorecorder recently for cheap and it's got a dead x-26 head on it. Otherwise in really nice shape. Im not planning on keeping it, figured it'd be a good one to fix and resell for a newb. I could just send the head off to Gib to get fixed up, but Im cheap and I like to tinker, so maybe I'll try my hand at making a mag head for it. I think I still have a Brush laydown head somewhere that I can maybe reverse engineer. I successfully rebuilt my 1-c after melting the coils,so maybe I can pull this off. Any thoughts? Potential problems ( aside from impedance, easily sorted)? Arguments about why it won't work while you furiously build your own? I'm open. Let er rip.

I've repaired over 250 mono heads now. You may also consider my full rebuild service.

Re: mag head for GI decks
Astatic made a mag head for GI turntables; the M-41. However, if your unit was originally wired for a crystal head, you'll have to change the output wiring to the cutting arm because crystal units operate on 180 VRMS - a LOT of juice; usually taken off the plate(s) of the output tube(s). This would smoke any magnetic head. Units like this that were originally wired for magnetic heads take the recording output post-transformer, not from the tube plate circuit. I think units like the Bell RC-47A had magnetic heads - at least the later units did. (I had one years ago that had the M-41.) Same GI turntable mechanism, but with a magnetic cutter.

I didn't realize you did crystal heads too. I'm trying to do this one on the cheap though, so it's gonna be diy.opcode66 wrote:I've repaired over 250 mono heads now. You may also consider my full rebuild service.
I might be interested in a set of 1-c coils though. My homemade ones work pretty well but I'm sure yours are way better.
