So… Tube Mods – Battery positive end up or down?
Firstly, let me say I know the answer to the basic question, but I want to get people’s views on mitigating risk factors.
In a hybrid tube, generally, the battery should go positive up, so the positive pin on the RDA connects with the positive connector on the battery. The body of the tube is therefore negative and the circuit is only completed if you press the switch, connecting the negative end of the battery with the negative body of the tube.
That way around, if there is any unnoticed…
