Description
Lot of 3 Amperex 7699 Vacuum Tubes - NOS/NIB - Hickock 539B Tested. The Amperex 7699 is a wide band push-pull amplifier tube for application in test instruments~ distributed amplifiers and computers. Stability of the Class A characteristics and low cathode interface are important features of this tube. The push-pull construction offers a high gain hand width product coupled with low output capacitance .. The screen and cathode, common to both halves of the tube, result. in high input impedance due to low internal inductance. A high dissipation of 3 W per section enables the tube to drive low load impedances. This tube is not recommended for use in applications requiring operation in the positive grid region.
