Pin #2 is a one of the two filament pins. It could be the one that goes to GND (chassis). It will also go to the rest of the filaments and the pilot light.
See if the chassis connection is missing. If not, every tube except the rectifier should have that connection.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
