Hi all...the picture is mostly good now. Contrast and focus are good. I can tell it's sharp because I can read small computer print on it just fine but...the picture is snowy...almost like it's not getting enough RF signal strength. I changed the tubes in the IF section and in the tuner to NOS but no change in fact, all of the tubes in the set have been replaced with NOS. I haven't done a thing to either the tuner or the IF circuit board. Any suggestions on a strategy to run this down?
