Hi
There is no way to add one more turn to the high
voltage transformer.this is a potted type high voltage
transformer .I think your thinking it's like a TV High
voltage transformer with the filement winding on the
core.
thanks anyway:Allan

will brighten up, but how long it'll last before

anyone's guess!
