Solid State Plug in Rectifier 5U4 5AR4 5Y3

This is great for those who want to try solid state rectification, without any modifications or soldering. Just plug in, rebias, and enjoy. If you are replacing a 5AR4 let the tubes warm up a little before applying signal. Makes it easy to change between tube and solid state rectification.

Solid State Rectifier Direct plug-in replacement for 5AR4, 5U4 and 5Y3 rectifier tubes in amplifiers with center tapped secondary power transformer.

Use when less 'sag' is desired in the power supply; just switch back to the tube rectifier when 'sag' is desired.

NOTE! Because there is no warm up of a rectifier tube when using this solid state device, it is critical that a standby switch is used that will allow the power tube filaments to warm up and generate an electron 'cloud' around the cathode before high voltage is applied. This will prevent 'cathode stripping' in the power tubes. It is a good idea to use a standby switch when using vacuum tube rectification, but it is critical when using solid state rectification.
