Hi Rob, the circuit shows how I built my Sussex and was not supposed to be a concise manual for other builds. For those with very few battery valves for testing it probably would be easier to simply apply the required voltage from external batteries applied to the EXT heater sockets. If I needed to test a large range of valves then the idea of having an external Heater supply capable of providing all required voltages would be a good idea.
