Hold the phone, everybody...
The speaker is OK. Some dummy (me) just connected one wire in the wrong place and then made an inaccurate measurement.
Really...it looked like those two wires were coming from choke (60), not from the speaker field. DUH. Well, even an old man who has been in the hobby for 41 years can make mistakes.
The radio is still silent, although it now produces a louder hum at the grid cap of the 75 tube (I think it should be louder still, but at least it is an improvement). It receives nothing. No AM noise. No SSTRAN at 660 kc. Nothing.
I plugged the 604 into an isolation transformer and started to hook up my signal generator. But when I attached the ground lead of the signal generator to the chassis (as the Philco specs call for)...the GFCI which protects the basement outlets tripped. So much for that. Now I'll have to figure out how to align this D**n thing...that is, if I can even get it going again.
Perhaps tomorrow, I'll put a small, working radio next to this 604 and see if I can pick up its oscillator in the working radio.
I sincerely appreciate the PMs with offers of speakers. Thank you...but I do not need one after all.
