Philco 77 hacked?
#21

Yes, field coil, I mean, sorry. I'm getting 3.4K on the Field coil connected to the output transformer and disconnected from it. The output transformer has four lugs on its bottom that connect to wires going to the speaker plug and two wires that go to a terminal strip on the frame for the cone. When I take the OT off of the pot metal housing behind the speaker cone and disconnected the wires from all points, I get about 175 ohms from two of the lugs on the output transformer and nothing on the other two, 3.4K on the wires that go to the field coil, and 0 ohms to .8 ohms on the wires that connect to the terminal strip.
From what you say, it sounds like I'm OK, then. After I read your post, I did some experimenting. I have a 1.01K FC Magnavox speaker and a Philco OT (part 32-7019) that I took off of my Philco 66 because I found the correct Philco speaker for the 66 on Ebay, and when I measured the FC and OT, I got similar measurements (not the same numbers, just similar results).
