The primary can be had in both a 120VAC mains only version and, for a small additional cost, a 240VAC mains only version.
The high voltage secondary is rated at 135V 53mADC, and it is designed to run into a voltage doubler supply.
The heater secondary is rated at 9V 1.3ADC, having been designed for use with a regulator for a very quiet DC heater supply.
The transformer is 3″ wide, 2.5″ deep, with 2″ extending above the chassis and about 1″ extending below. It is designed for horizontal mounting, requiring a 2.1″ x 1.9″ rectangular chassis opening and four holes arranged in a 2.5″ x 2.0″ rectangular pattern around the opening.
