Treasure 274B-Z replacement notes
- PSVANE Treasure 274B-Z is a rectifier tube matched pair for compatible tube amplifier power-supply positions.
- Use it only where the amplifier or power supply specifies 274B or explicitly allows this rectifier family.
- Rectifier compatibility depends on filament current, rectified current demand, filter capacitance, and socket wiring.
Before ordering Treasure 274B-Z
- This product is listed as a matched pair, but many amplifiers use only one rectifier tube, so confirm the required quantity first.
- Check the amplifier manual for 274B compatibility before replacing 5U4G, 5AR4, GZ34, or another rectifier label.
- Do not install a different rectifier family just because the tube base fits the socket.
