420b's

[Old Guy]

"B's" were late, 1974 and after, and are the premium 420 using a 16 inch frame and the cast motor of the 416-8B.

I'm pretty sure the Madrid was out of production by the time the 420-8B came along, but as soon as i say that an "odd duck" will surface.

My bad. I think you are right, but won't guarantee empty boxes weren't sitting around and stuffed later...have seen enough weirdness to be careful about absolutes. But have never seen a Madrid with 420B. only 420A. to be technical, 420-Z.

Hmmmm....I have a pair of 872Bs, my first Altecs/first hit of crack in fact. I could swear that they are the newer style frame without the integral tweeter.....

They probably are. The '75 reference guide shows 3 possible loads for 872B, two of which are in 16 inch frames.

AFAIK, the only 420 with the tweeter coaxially strapped across it is the 420Y.
