The NEW, RF Parts Company 3-500ZG and Taylor Tubes 3-500ZG tubes are the most rugged tubes of this type available.  They are an improved version of the 3-500ZG offered by RF Parts Company, from 1993 to 2019.  This newly revised version has had a failure rate of less than 0.05% during the three years that we have been testing, matching and selling them.

These tubes are a Heavy Duty Graphite Anode version of the original Eimac 3-500Z, and it has a stronger Anode stem-support to add to the tube's ruggedness and stability.  The Graphite Anode, Grid, and Filament are virtually the same as the Graphite version last offered by Eimac, and is interchangeable with this vastly improved transmit tube.
