Zenith 1000 User Manual

ZENITH 1000/3000 TRANS-OCEANIC RADIOS
INSTALLING NTE TRANSISTORS
To replace an OEM transistor with an NTE transistor, note that the NTE transistor
only has three pins. The BASE is in the middle, and offset from the EMITTER
and the COLLECTOR.
To install the NTE transistor in a Zenith socket with three pin sockets, bend the
pins of the transistor as shown. Make sure there is no contact between the pins.
When the pins are aligned with the socket spaces, gently push the transistor in
as far as it will go. The pins will not go all the way in, so the transistor will sit
above the socket, not flush with the socket. This is OK.
