Counter clock-wise from the filament transformer: four AC chokes (-B voltage, Filament, HV Control and Common), two terminal blocks for junctions, 12Vdc power supply, Stand-by and Power switch, Zener diode and 50W heatsink, homemade PCB with ALC circuit, 125vAC ALC power supply, Filament Chokes.
Hole above two terminal blocks is where blower fits on top. Two holes on upper left are beneath 3-500Z (see other pictures).
Input tuning PCB and blower on right side.
Test front panel; just for fit and testing. A new panel will be made that is taller and fits better. Metering, switches, and tune/load dials put on for fit and testing.
