Solid-State replacement for 5AR4 5U4 5Y3 rectifier tube

Solid-State Rectifier replacement for 5AR4, 5U4, and 5Y3 rectifier tubes. This unit gives you a reliable, solid-state device that will eliminate power supply sag and increase the voltage output over a tube-based rectifier. This will raise the supply voltage anywhere from 10 to 50 volts, so re-biasing and even replacement of some components may be required. If you are unsure, please consult a qualified amp tech. When using this device to replace a vacuum tube rectifier, you should always use a standby switch in the high-voltage circuit to allow for a filament warm-up period in the amplifier tubes. This will help to prevent cathode stripping of the power output tubes.
