After an alignment I noticed that from about 1000 kHz and lower freq. the reception will work at times or not. Above 1000 kHz does not fail can always receive.

I had a VOM lead connected to chassis with meter on, with the other probe I would touch the #2 pin (plate) of #77 tube and make it (lower freq's) come and go. Also on the OSC coil I could touch pin #5 (to tuner) and it will cut out, touch pin #4 it will cut in, this is all to do with the lower freq's. If I touch pin #1 or pin#2 has no effect (tickler). Touching pin #3 will also make it cut out.

I don't know if this is a tube (#77) problem or the OSC coil or what.

I have a 6200 ohm resistor to ground instead of an 8000 ohm on the tickler coil.

I have rewound the tickler coil on the OCS coil it was open.
