The schematics posted here seem to not be the right ones.  I just purchased this on Ebay, and the chassis tag clearly shows 100.384.

This radio has 7 tubes, and a power transformer.  Tubes: 5Y3, 6J5GT/G, 6J5, 6K6, 6SK7, 6SQ7 AND 7H7.

The schematics shown here show series string heaters and completely different tubes.

Can you please review?

Thanks,

Ron Scott
