I have just started work on the circuit design. I will rectify and smooth the outputs, but I'm wondering if the slight ripple will have a detrimental impact on the valve tests. Does anyone know?
If I have to use a regulator for one or more of the circuits (heater, plate, control grid or screen grid) then I'm going to need anything from 30v to 240v. Is there an IC that can manage 240v? The highest value IC I know of is the LM317 and that can only be turned up to 57 volts!
Thanks
Nick
