I've got a set of 206AX coaxials. Someday I'll build a set of corner cabs for them.
It's a 122 AX ... the "economical choice" unfortunately according to one of the brochures www-records linled to (thanks for that info) ... it cost $54 in 1954 ... can handle up to 20 watts ... the brochure says 16 ohm ... but the plate on the back says 12 ohm ... FWIW ...
