I'm in the process of restoring the BOL record player on this model. There are two screw terminals on the backside of the chassis resembling what a standard antenna terminal strip looks like. This is shown on the components drawing on the attached PDF file of the schematic just to the left of the XXD tube socket. This is where the two thin wires from the tone arm get connected....one I believe comes from the photo cell, the other from the exciter lamp. My problem is I'm not getting any voltage readings from those two terminal strip connections. Which, of course, means the exciter lamp won't light when trying to play a record. Now just for an experiment, I took a 6 volt lantern battery, and gater wired the two thin wires from the tone arm to the two connections on the battery. Viola! The exciter lamp lit, and the BOL came to life, playing a record remarkably well with no adjustments or any restoration to the tone arm.
Does anyone have any idea what I could be missing that I'm not getting any voltage readings on those terminals? I did a preliminary check of the (#19) light reproducer coil and got continuity. Has anyone else had this issue on a BOL? This is my first BOL restoration. Thanks!
