Whit | Re: Triode switch A.S. Nothing complicated about wiring a triode switch. Just need a double pole switch. Disconnect the usual screen supply from the screen pin and connect it to one end of the switch, connect the plate via a 100 ohm 1 watt resistor to the other end of the switch, and then connect the center of the switch to the screen pin. ie. you either feed the screen from the usual source, or from the plate via the 100 ohm resistor. Only warning, and you should heed it, is that the ratings for triode connected pentodes are usually much less than the usual full pentode ratings. I've run triode/pentode in Champs without any trouble, but if the amp you're working with is already pushing the limits of the pentodes (high plate voltage, abundance bias current) then you could be in for some trouble just flipping it over to triode connection. ...
