I picked up this circa '57 17" wooden cabinet Olympic (model 17TU97) B&W TV. As you can see, it's missing the channel knobs and a bezel that goes behind the side knobs. I suspect these parts will be difficult to find. The CRT test weak; but, should produce a picture. When powered up on the variac, the B+ is low (probably bad caps) and there are no filaments (probably an open resistor or tube filament). This set used two selenium rectifiers in a voltage doubler configuration; but, someone jumped them out with silicon diodes. And, they left the old selenium rectifiers in circuit; which, is a no-no.
Anyone ever worked on one of these? This Olympic set looks to be a cheaper built brand than RCA, Zenith, etc.
