I have a 12.6V CT 2 Amp Filament transformer.

I want to use 6.3V to run one 6.3V tube, and the second 6.3V to run another 6.3V tube.
Each tube requires 1.8A.

If I use both 6.3V from the transformer, does each 6.3V handles 2A ?
Or each 6.3V can only handle 1A ?
 
Thank you



You mean wire the 2 tubes in series ?

As far as the current calculation is concerned, you could wire them in series. There is a possible concern that they might not divide the voltage equally. So connecting one of the tubes to one 6.3V winding, and the other to the other winding, would be better. But the basic answer is yes, the transformer could handle the load.
