420b's

[analog addict]

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.....

Why? Did you fart?

Seriously nothing to be sorry about.

Well for some yes and others No.. But in general if someone posts the same thing (Duplicate) first, I like to place the credit were credit is due !

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.



Here's a 420-8B compliments of Wardsweb: Altec 420-8B
