38-690 Missing amp and 14" woofer
#5

The 38-116 speaker to replace the 38-690 woofer is a good suggestion. The extra control transformer windings could supply the field coil current. A voltage doubler circuit could be used if necessary, and the 25 and 35VAC windings on the jukebox chassis could be placed in series.
