for heath by JBL

[Hot97Rules]

I have a pair of heathkit speakers with JBL drivers in them and I was wondering if anyone could tell me which JBL models they are. The model number on the woofers is 401-133 and the tweeters are 401-132. They look to be d123s and le-20s respectively but thats just a guess. any help would be greatly appreciated.

Hey, that's a Dynaco A-50 those drivers are sittin' on!

Vent on the back is throwing me. Maybe 123A-x? If so, they're L88 equivalents:

Tweet's LE20-1.

That's definitely an early 123A, but with a strange magnet back (with a "ring" cast in).

Definitely looks like L88 equivalent.

That woofer is a remarkably good E-wave candidate...

Indeed, we were eWaving L88s before there even was an eWave:

I've never seen it, but that may be what's under the stock JBL "can."
