Subject: [R-390] Carrier Level Meter Issues

On my 1967 EAC S/N 4996, I have zeroed the meter as follows:

 

I tuned the radio to a dead space, unhooked the antenna and turned the RF
gain fully counter-clockwise.  I then adjusted R523 to zero the meter.

 

However, when I tune to 2 different local (strong) AM stations on the BCB,
even though I start to hear the audio when the RF gain is at 4.5 and it is
heard very loudly at 7, the carrier level meter only starts to register when
the RF gain is at 7.5 and at full clockwise, only registers 40 db.

 

I would like to troubleshoot this but don't know where to start.  If anyone
could guide me as to what to check, I would be most grateful.

 

Thank you. 

 

Gary
