Are your electrolytics marked Sprague by any chance?

Mine are Solar and the electrical tape over the connections would make them replacements.

the electrolytics should be 6MFD.

I only have 10mds, +/- 20%, on hand. No prob?

BTW, my cabinet is stamped JUN 26 31

10mfd caps should work fine. I'm not an expert, but the increased capacitance should just mean better filtering to a point. Philco probably used the lowest possible value that worked well to save on costs.
