Too much noise between stations!
#2

Noisy tubes will often not fail on a tester  Try swapping the tubes out one-by-one with known good tubes, preferably from one of your other Zenith sets that don't have this issue.  Also try cleaning the tube pins and sockets.... often I'll use some of these small brushes moistened with contact cleaner for the sockets:
