On the component side, resistors that will get warm (like the cathode cutoff and screen safety resistors) should be kept away from other components that may be sensitive to heat. Low voltage components should be spaced away from those carrying higher voltages (note the sequencer components on the left, and the rest mounted on the right). The bias regulator transistor is placed in the air stream of the exhaust fan.

Computer-style jumpers are used to adjust the filament supply resistance for proper emission.
