The wind chest for the RF deck has remained very clean somehow. This area is pressurized during operation and the cooling air is forced from the blower, in from the square black opening on the right, past the airflow switch, and up through the round fitting on the 4-1000 socket. The square boxed area at the inside left is the grid circuit compartment. One side of the 4-1000 filament is grounded. The filament transformer is rated 7.5VAC at 25A.
