Updated ‘Tube Bible’ Available from EIMAC

Also on the tube front, the EIMAC division of CPI has released an updated edition of its handbook, “The Care and Feeding of Power Grid Tubes.”
The handbook, which the company says is considered by many to be the “tube bible,” has a new section that covers Inductive Output Tubes (IOTs). Updates include information on oxide cathodes, grids, anodes, vac-ion pumps and cooling.
The book available through EIMAC global distributor Richardson Electronics and individual copies may be obtained by contacting Richardson at (800) 882-3872 or by e-mail request to [email protected].
