Here's a few pictures after the transmitter was dug out of the garage, and just moved into the lab for repairs and restoration.

The images show:

1. the power supply area from the front including the four sockets for the rectifier tubes, the rectifier filament transformers below them, the final and modulator chokes to the left, and the space to the right, where the modulation transformer goes. The transformer is very heavy and will be moved shortly.
DETOUR: It was decided to move the rectifiers to the rear of the unit, behind the modulator tubes. The filament transformers and broken chokes were also removed from this area in order to clean it out.

2. The power supply operating control panel. Controls from left to right are:
-TOP ROW: PLATE OVERLOAD and RESET button, G2 OVERLOAD and RESET button, FUSE 1 indicator lamp, TEST switch, ON THE AIR indicator, LOW/NORMAL power selector, AIR SWITCH OPEN (blower interlock), CW/PHONE switch, FUSE 2 indicator lamp, MOD HV RECT FIL indicator and switch, MOD AND FINAL BIAS indicator and switch.
-MIDDLE ROW: POWER 1 indicator, POWER 1 switch, FINAL BIAS adjustment, FINAL SCREEN adjustment, MOD BIAS adjustment, POWER 2 switch, POWER 2 indicator.
