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.
