I’ve been working on repairing these 3000H diaphragms for my Altec Sevilles. I’m getting a good signal reading across literally everything and OL from post to post after connecting the tensile. The tensiles read fine up to diaphragm, and the diaphragm lead outs (picture 2) read fine as well. It’s driving me nuts, it’s this potentially a microscopic irreparable issue inside the voice coil? If it was in the voice coil why would the lead outs from the voice coil not read OL??

I first got these Altec Sevilles years ago and thought they were cool. I had them playing through a generic amp, not great speakers etc. I’d not really had much home audio knowledge before that. Many, MANY hours of reading later, here’s where they are at. Over the years I’ve tweaked more things than I can remember. All basically built around these speakers. Current signal chain:

- Yamaha YP-D6 with OC9XML moving coil cart
- Luxman LE-117 phono pre (massively underrated but hard to find)
- passive pre (considering going to a TVC soon, not sure. I’m losing negligible amount of quality with a passive good quality pot and adding zero extra flavor)
- MC240 with mullards
- Altecs with horns crossed fairly low so the woofers hit most of the high mids
- Aperion ribbon tweeters handling all the air, barely audible but there.

I feel like with this setup I can get tons of warm realism from jazz and anything with acoustic guitar, and also get good tone from “audiophile” level more modern recordings. The jump I got in this system completely removing an active pre amp (tube) was MASSIVE. It seems like the mc240 colors enough that I don’t need added gain staging or juice before it at all, and it’s more about the signal getting to power amp being as untouched as possible and clean.

I also play my guitar through this setup, the jazz clean tone is bananas. DI converter straight into the Mac and out the altecs. Low end rolled off, highs rolled off.

Thought I’d share, thanks for looking!
