Philco 60 code 121 IF's
#13

I thought I was doing ok. I have not removed the antenna coil, the coil ohms out great, but I do not see the coil which is rated at .7 ohms. on the schematic it is on the bottom on lug #4 of ant. coil. How important this is.

I was able to wrap a wire around the 6A7 then connected to my freq. counter and it worked ok, but not above lets say 1300 khz and above, if I touch the 6A7 cap or the #5 lug on ant. coil it will work ok. I used a transistor radio to test the osc as well worked ok.

Also I set the freq. generator to 460 khz and touched the grid cap of the #78 IF tube I get it loud thru the speaker, when I touch it to the 6A7, it is about 50% less. I do not get the 460 khz tone when connected to the antenna clip.

I can hear one station but very faint, it is at 1370 khz, on the dial as well. That station is the strongest where I live. If I turn the dial it will disappear. So the signal is right on. I do not get any hiss from the speaker either.

Is there a diagram for the band switch some where.

Thanks for helping me out this one is a bummer, just a year ago I restored a "60" went fine. I'm just not a good trouble shooter.

Seems to me the trouble is in the front end????
