Hi CArey:
If it only on 10M, it is unlikey to be an audio issue. More likely an
issue related to one of the bandswitched stages. Have you tried peaking
the inj and rf amp trimmers for 10?
10 is pretty quiet these days here but regulart QRN should show up just
like it does on 20 or 15 when they are closed down.
I use R-4a ser # 6131--with the transistor VFO. Original owner.

well my r4a is turning out nicely but i am not sure about 10m. i have
to turn the volume up to almost 2 o clock to here any noise. is the
r4a deaf on 10? or do i maybe have a audio problem? the serial is
2952. i noticed some circuit difference when comparing it to another
parts r4a i have. this one also has one more tube the other dose not.
i am guessing this is a early model. does anyone have the same situation?
