Hi, does anyone have any idea how much current/power can be drawn from the
dual primary of a plate transformer from one leg of the 120V to the (center
tap) 0 volt connect when both windings are in series for 240v? With most
amplifiers you will see the blowers/fans run off in this way. The reason
being, I
have a 120v filament transformer for a single 3CX800 tube. The total
primary current would probably be less than 200 mills. Since the 3CX800 is
13.5v
at 1.5 amps, that is about 21 watts, I would assume the primary wattage would
be near the same, about 21 watts. 21 watts at 120v is only about 200 mills.
Anyone see any problem with running the filament transformer using the
plate transformer 120v tap and the center tap on the dual primary? The
numbers
indicate it should be possible but am I missing something?
Lou
