SOLID STATE RECTIFIER
Solid State Rectifier Replacement for 5AR4, 5U4 and 5Y3
This solid-state rectifier can be used as a direct replacement for the 5AR4, 5U4 and 5Y3 rectifier tubes in amplifiers with centre tapped secondary power transformer.
Use these when you are looking for less sag in your amp. I have used both tube and solid state and there is a definitely a different feel between the both, a cheap mod for your amp if only to try them,
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.
