: : : :  : : : : : : : :Sir A.J. . . . . . : : :You now say . . . . . : : : :Going to try a PM first. Plan to attach Audio xformer to #97. : : : : :Since you are the one with THE set and the eyes . . . I’m blind at this end . . . and can’t physically inspect that set. : : :Do check for the presence of the AF output transformer item #105 ALREADY being in the set and hooked up to plates of the push pull pair of output tubes. : : :If such is the case, then you are ready to go, as is . . . no “ audio transformer” needed, BECAUSE , that #105 IS the AF output transformer and has converted the high impedance matching to that set of tubes on down to an ~ 4 ohm value required . : : :Thereby, making it already prepared for the hook up of a PM speaker of that approximate matching impedance to the mentioned terminal connection NUMBAH 97 ! . : : :If the set is developing B+ to all stages, but NO stations coming in, then your first test of the audio section ---- speaker ----- and B+ presence, could be the spittle moistening of a finger and giving a “Wet Willie” to the grid leak resistor terminal on the tubes grid side. : : :If a loud hu m m m m m m m doth emanate forthwith . . . . . congrANulations . . .. on now having the set working from that point on, thru to the speaker. : :One then has to further figure why the RF portion is inoperative. : : :That hasn’t been heard in possibly up to 80 years ! : : :ZUJ’ing : : : : : : : : : : 73's de Edd : : : : : Try something. . . . if you sit here and think too much, you'll create a problem that wasn't even there in the first place. :. : : : : :  : : : |
