The speaker Bob (klondike98 ) linked to is for a 14LZX, not a 19LZX. But it could be adapted to use with a 19LZX with a little work. You would have to replace the dual speaker setup with a single 10-1/2 inch speaker with 1140 ohm field and single-ended output transformer, and make a few changes to the control box in back of the speaker cabinet.

$75 is a very good price for that speaker cabinet, which is just as hard to find as a 19LZX/19TX speaker cabinet. It wouldn't be cheap to have it shipped from coast to coast, however.

But then, I would not trust that flat cable after 81 years - this cable's conductors has the infamous rubber insulation. You would have to replace the cable...and you won't find a flat cable with conductors large enough to handle the voltages and currents involved...so you would have to settle for a round cable, which won't look original but will do the job.

Or just add the 8 inch speaker inside the chairside cabinet and have a 19LZ.

Either way, a bit of work will be involved...but worth it, I think.
