Pye Mk6 Television Camera Power Supply and Control Unit
The CCU (left) is a valve transistor hybrid, the main video path being valve. The switch that can be seen in the interior is the camera cable length adjustment. Weight 26Kg.

The PSU (right) is a conventional transformer rectifier type, but the regulation is done by a switching SCR (silicon controlled rectifier). Comprehensive monitoring of the currents and voltages is provided by the large switch and meter. The meter is arranged with a red mark in the center of the scale and each measurement should fall in that mark. Weight 45Kg.

There was an inverter for tube high voltage supplies.

Both units have ventilation fans with filters in the bottom section.
