In restoring a Philco 37-10 I find that the 6H6G discriminator tube is not wired as shown on the schematic. The connections to the plates and cathodes are reversed; my set has the plates going to 2 meg resistors 60 and 61, and the cathodes going to coil 48. The schematic shows it the other way around. Is this a drawing error, or a modification? I hope someone can shed some light on this. I just today got the radio to playing (it seems to play well), and have not yet reassembled the Magnetic Tuning apparatus (I need a new dial from Mark Oppat.) Thanks for any help. Charrday
