Vacuum Tube - 12BZ6, Pentode, Semi Remote, RF
New-Old-Stock (NOS) tube.
The 12BZ6 is a high transconductance, semi-remote cut-off, pentode amplifier. It is designed for service as an automatic gain controlled IF amplifier in 150mA. series heater operated television receivers. Thermal characteristics of the heater are controlled such that heater voltage surges during the warm-up cycle are minimized provided it is used with other types which are similarly controlled. With the exception of heater ratings, its characteristics are identical to the 6BZ6.
