There are a few Eimac Application Bulletins on the web, at:
http://www.cpii.com/eimac/eiapps.htm along with other useful information 
and a limited FAQ.

     *  AB5 - Eimac Tube Performance Computer
     * AB16 - Water Purity Requirements in Liquid Cooling Systems
     * AB17 - Fault Protection
     * AB18 - Extending Transmitter Tube Life
     * AB21 - Conditioning of Large Radio-Frequency Power Tubes
     * AB24 - Prolonging IOT Life - Optimizing IOT Operation
     * AB25 - 3CPX800A7 Recommended for FM Broadcast
     * AB27 - Shipping and Handling
     * AB28 - Hi-Pot Testing of High Power Tubes

AB17 is the much-debated one about "glitch protection", but the list 
doesn't include the ones about the 3x0.5.
