All good info, thanks, Roger. I'm getting 182 vdc consistently at test point, but sometimes when I've had it off floor a while and power it up, takes a few minutes until audio comes on. When it does comes in gradually over 5 seconds or so like when a tube is being first turned on. Strange! Sig strength meter works in interim, but not line level meter.
Regards,
Terry

Terry,
The signal strength meter is off the fourth (last) IF tube before the detector. The line level meter is the last of the line audio channel. As you do not hear the audio in the local channel the problem is before the line and local channels split and after the signal strength meter. I vote for a cold solder joint or leaky cap. Time for some trouble shooting.
