Philco 46-480 Electronic Restoration
Posts: 486
I forgot to make mention of it the other day, but last week I corrected another error on my schematic (applies to both Revs 0 and 1). I had thought, from looking at the Philco schematic, that pins 4 and 6 of the 7H7 used as the second IF amp were connected. I realized when comparing against my physical wiring notes that they are not. I also verified using the Rider's version of the schematic that they are not tied together. I'm sure that the original Philco schematic was correct, but this particular crossing was blurry and it looked to me to be a node. Anyway, I've attached the corrected schematics.
