[R-390] R-390A Carrier Level meterindication drifts upward during set warmup

[Henry Meiseles]

The zero signal indication on my R-390A (Amelco, Inc.) climbs up to a zero 
signal level of 40 dB after about 15 -20minutes from turn on. Haven't yet 
made any effort to measure my way to the fault source. If anyone has 
experience remedying this problem please let me know.
