Philco 118x floor model restoration
#25

its the 970.

i hooked it up to my oscilloscope and managed to see a nice fat wave, which as i turned up the audio knob would start to distort the wave.....i admit i know next to nothing, but that seems like a good thing. like the wave was at that point carrying a signal.

strangely, when i would fiddle with the different band knobs, the sine wave didnt change at all. i sort of expected a change in frequency or something, but it pretty much stayed the same until i got to some of the higher frequencies. im not sure if this is normal, or if its my nearly complete lack of understanding of the subject, or if the analysdt is not working properly.
