I have an R4B that in the last 5 or so years has had what I think is excessive
drift in the S-meter zero. I saw a posting from Garey that mentioned checking
and/or replacing V4 or V5. I checked both and they had good emission and no
shorts. When I first turn on the radio, the meter reads around S-6 and works
its way down to eventually near S-1 with no antenna. It takes at least half an
hour to get to the S-1 mark. Also if I set the 'meter zero' earlier that the
half hour, It will be off if the radio is left on longer. I suspect the the
meter should 'settle down' faster than that. Has anyone else noticed this
problem and what did you do to correct it. I didn't replace the tubes, and
maybe that is my next step.
I appreciate any suggestions you might have.
