ONE NEW solid state rectifier for replacing a 5AR4, 5U4, or 5Y3 vacuum rectifier tube in vintage radio power supplies. A solid state recetifier reduces power consumption and damaging heat, and increases the output of a vacuum tube rectifier. To help prolong power tube life when using a solid state rectifier one should consider use a standby switch in the power supply to allow filiment "warm up" voltage prior to applying high voltage through the recetifier.
