What is a tripler?
In some TVs, the flyback transformer only generates about 6-10 KV AC which is then boosted by a diode-capacitor ladder to the 18-30 KV needed for modern color CRTs. The unit that does this is commonly called a tripler since it multiplies the flyback output by about 3 times. Some TVs use a quadrupler instead. However, many TVs generate the required HV directly with a winding with the required number of turns inside the flyback transformer. Triplers use a diode-capacitor ladder to multiply the 6-10 KV AC to 18-30 KV DC. Many triplers are separate units, roughly cubical, and are not repairable. Some triplers are built in to the flyback – it is probably cheaper to manufacture the HV diodes and capacitors than to wind a direct high voltage secondary on the flyback core. In either case, failure requires replacement of the entire unit. For external multipliers, the terminals are typically marked: IN – from flyback (6-10 KV AC). OUT – HV to CRT (20-30 KV DC). F – focus to CRT (2-8 KV).
