572WB Tube Substitute & Equivalent Information

The 572WB tubes are high-performance replacements for standard 572B tubes and are fully compatible in all applications where the 572B is used. However, the 572WB offers several enhancements that make it the superior option:

  • Metal Base vs Plastic Base: 572WB’s machined aluminum base improves heat dissipation and structural integrity.

  • Gold-Plated Pins: Superior corrosion resistance over the standard nickel-plated pins of 572B tubes.

  • Higher Voltage Tolerance: Each 572WB tube is hi-pot tested and certified to handle increased standoff voltages.

  • Improved Reliability: Teflon wafer inserts ensure long-lasting pin stability, reducing the chance of failure under load.

These factors make the 572WB tube equivalent to the 572B in functionality—but superior in performance and longevity.
