OK, there's one LAST thing to do before I turn this thing on for the first time:
there's a 1 Mega-Ohm resistor in the tuning eye socket that is almost always
open or has drifted upward in resistance. This provides the voltage drop that enables
the tuning eye to open and close as a station is tuned in. It's an easy replacement.
Here's the new one in place in the socket.
