A tripler is device used to multiply (x3) the output voltage from a winding in a TV flyback transformer (LOPT) in order to supply EHT (Extra High Tension Voltage), typically 25kV, to the final anode of cathode ray tube in a color television receiver. With the introduction of diode split flyback transformers in the 1970's they have largely fallen into disuse, leading to a more reliable receiver designs, devoid of a component which once accounted for a significant amount of failures.
