Hello Group,
I have ''restored'' a number of Hallicrafters receivers (SX-28,SX
42,SX-43 )and also some National's.---They all run pretty well, but show the
same symptoms.----

Normally the receiver is run with the RF Gain all the way up and the AVC in
the 'ON' position.-----When turning the AVC to  'OFF',the volume increases
on the strong stations and the Audio gets quite distorted.---this can
brought back to normal (no distortion) by turning the RF Gain down.---The
point at which this happens,is very distinct as you turn the RF Gain
down.-----This symptom occurrs on all of my receivers.

---Question,---Is this normal ????---- Or have I missed something  while
''restoring'' those Radios.---They have all been ''re-capped'',but I
normally leave the resistors alone and check the tubes by substituting with
others I have in the Junkbox.

Tnx fr any help that is out there in Hallicrafter Land.--- Olaf,KF4TP---
