Philco 46-480 Electronic Restoration
#23

Nice job on the schematic! I hear you re the difficulty in determining wire crossing vs "node" on some reprints of the originals. Please do check the resistance readings for the output transformer, they may be incorrect. I would not expect a reading of 11.25 Ohm for the primary and 510 Ohm for a secondary that connects to a 3.2 Ohm speaker. You are doing a great job on a gargantuan project!
