No the zener serves a delay function to prevent any real AGC voltage on the tuner until signal strength gets high per the manual.
Another clue- if I add a 9 volt battery to the pulse gate terminal that brings more voltage into the gate transistor collector and tap the connection I can see it shoot up to 10 or more volts. The HOT winding is so simple but for some reason I'm only getting a pulse of a few volts here instead of the 30-35 expected.
