The place is called Jackson Speaker Service. I used them to rebuild the speakers on my '62 Starfire & they did a great job.

I almost used that Wonderbar guy, but the more time I spent reading his site, the more I thought he sounded like the Unibomber.
Instead, I used Barry Dalton, the Antique Radio Doctor. He's done a couple of radios for me.
He's a super-nice fellow, has reasonable rates, & a very fast turnaround. He's in OR. Drop him a line when you have a chance:
