It's Sam's that is incorrect. The photo in Sam's is missing one connecting wire and a few other parts.

This chassis was available for over 2 years under at least 4 brands and probably more, so production changes are expected.

Your former recapper must have lengthened the wires, because the factory wires are too short to get a full view of the underside.



Your set is missing a black wire connecting the B+ limiting resistor 7.5 Ω or 10 Ω resistor and the 100 µFd electrolytic.

Also below are photos illustrating the chassis with the 6C5 and 12AT7 tuners.

If you or anyone wants a higher resolution copy of these, just shoot me an email, as VK compresses photos. If you need see a better view of the underside of the three tube sub-chassis, I'll do it, but it may take a week or so, as I have to clear my workbench first to unsolder and mark the seven leads.

Sorry for the rant, but I've gotta find a source for traditional lamps. These pigtails make color codes hard to read and give you a completely different color when taking two photographs shot seconds apart, without touching the lights.

You might try using LED lamps. They give much better color rendition than compact fluorescents. It is a more pleasing type of light as well.
