University 6201 series HF drivers

[UncleArt]

I have a pair of the cast-aluminum frame university 6201's that I love dearly, and have nursed back from death more than once, but it appears one of the HF driver's voice coils has opened up AGAIN, for the third time.

Never mind the huge b*tch it is to take them apart... but the last two times, I found the "open" within a few turns of one end. Both times, I was able to simply discard the (minimal) length of wire following the break, retack the end to the terminal, and keep on going.

The very minimal loss of voice coil (maybe up to eight inches after the second repair) was negligible in as much as my ears can tell.

However, I now clearly hear that this same voice coil has either burned, rotted, or broken open AGAIN. It seems like a bad shoelace, that keeps getting shorter and shorter...

Obviously, this coil has been abused and or beaten on to the point where it cannot be trusted.

I'm not sure I could be trusted to unwind the whole thing, count the turns, size the wire, and rewind it neatly enough to get it back in the gap, and actually work.

Does anyone know of a source for a diaphragm/voice coil assembly that fits the university 6201's coaxial HF driver? At this point, I'd even be open to a compression driver I could run "through the hole" and feed out through the original horn. If I need to redux both speakers, that's ok.

I would rather NOT, however, cut the HF unit loose, add a separate tweeter, and leave those pretty horns behind as 'useless appendages', which would be the easiest fix. Again, though, I am not married to the idea of them being "all original".

FWIW, I've found that more than one 6201 hocked on fleabay, "as is', come with perfectly useless, open voice coils on the HF drivers, yet the seller claims "they sounded fine to me".

Anything you've got would be appreciated.

Thx

Maybe this works for you.

I don't know the 6201, but is the HF similar to a more common driver? Maybe a stand alone driver. EV or similar.

Reason I ask is that I have a pair of old Fane tweeters that are obsolete and no diaphragms to be found. But I managed to get the JBL 2404 'frams to fit and they work great. It did take some shimming, but was not too hard.

I may be onto something...

I dissected an older University 301, and extracted a very nice HF driver, all self contained, with the absolutely wrong threads to mount to/on/near the 6100.

I believe with the driver and horn in hand, a trip to the local plumbing supply place may get me on the right track.

The Voice Coil in question, for what it's worth, is done for. At some point, it snapped again, and managed to get all loose and bunched up in the gap. I have a bird's nest of loose broken wire. I won't be rewinding this thing.
