Here
is the back of the 12-S-232.Notice the 670 ohm speaker (Zenith part number
49-183AB).This
speaker is nearly impossible find because it was only used
on the 12-S-232. It is always easy to tell a piece-meal
12-tube Walton, because this speaker is usually replaced
with another one, and
the silvery-white painted model designators are rubbed off!
