Full Wave Rectifier

5AR4 Full Wave Rectifier The 5AR4 is a heater-cathode twin diode designed for full-wave rectifier opertion. High output current and small size make this tube especially suitable for compact amplifier designs.

The tube manufacturer chooses these values to provide acceptible servicability of the tube, taking responsibility for the effects of changes on operationg conditions due to variations in tube characteristics. The equipment manufacturer should design so that initially and throughout life no design-maximum value for the intended service is expected with a bogey tube under the worst possible conditions with respect to supply-voltage variation, equipment component variation, equipment control adjustment, load variation, signal variation, and environmental conditions.
