I always trouble shoot by swapping tubes...not using a tube tester.

Both my A and B do this...interested in a fix shortcut...have not really

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.
