Carey -
Do you have a shorted RCA plug in the MUTE jack on the back panel?
S/N of the R-4A? There are four versions, two each of a similar design.

well guys i picked up a couple clean pieces of gear. both of them have
problems. i am hoping with a little help from the list i can get them
going. i figure i should start with the receiver. after a lengthy
visual inspection i can find no broken wires burnt resistors or any
thing else. although the ob2 is yellow instead of blue like a oa2. all
the front knobs seem to have some effect. the volume increases the ac
hum. the passband and notch seem to change the sound. am and ssb seem
to make a difference also. now when it is turned on the s meter pegs
to right and stays there. i am not asking for hours online repair just
a kick in the right direction. any help with these items would be most
appreciated.
