5.2 (A6 and A7, A8 and A9 with
upgrade) UHF Amplifier Trays (1294-
1112, 1294-1113 or 1294-1114;
Appendix C)
When testing the UHF amplifier trays, the
other circuit breakers on the AC
distribution panel, and mounted toward
the rear of the cabinet, should be turned
off. Circuit breaker CB3 applies power to
(A6) the UHF amplifier tray from J5 on
the AC distribution system. Circuit
breaker CB4 applies power to (A7) the
UHF amplifier tray from J6 on the AC
distribution system. After upgrade, CB5
applies power to (A8) the UHF amplifier
tray from J7 on the AC distribution
system and circuit breaker CB6 applies
power to (A9) the UHF amplifier tray
from J8 on the AC distribution system.
The UHF amplifier tray should be turned
on into a dummy load of at least 300
watts to verify that the tray is
functioning. Prior to testing, disconnect
the amplifier tray at the UHF tee and
connect it to a dummy load of at least
300 watts. Preset S1, the AGC switch on
