Time to call in the experts!  I've tried various combinations of =
Sylvania 6JB6's, new and used, and 12BY7A's etc and yet final =
neutralization escapes me.  20 and 15 are extremely touchy when tuning.  =
In addition the S-meter does not wish to stay at zero even after =
swapping 6BZ6's around.  S-meter pegs full full scale when the RFG is =
full CCW; Drake says meter should be around 50 over 9 or so.  Last but =
not least - when transmitting the S meter rests about S-9 or so with no =
mic audio rather than at 0.

Suspect AGC problems which should not effect neutralization.  Just =
thought I'd toss out all the problems at once.  Comments greatfully =
accepted.
