SPEAKERS
¼” speaker cable jacks. Use a ¼” speaker cable to connect your speaker
cabinet to the amplifier using these jacks. If you use one speaker cabinet, either jack is
acceptable.
NOTE
– never turn your amplifier to OPERATE mode (“1” / DOWN position on STANDBY)
without connecting the amplifier to a speaker cabinet or suitable dummy load! Failing to do
so may damage your amplifier!
NEGATIVE FEEBACK (NFB)
is a 3 way switch to select different NFB resistor values:
27K (LEFT), 49K (RIGHT), and No NFB(MIDDLE).
No NFB will give the amp a louder, more gainy characteristics. Wild!
FULL / HALF
switches the power output of the power amp. HALF mode configures the
power tubes to run in triode operation, and this negates any need to reconfigure the
IMPEDANCE SELECTOR.
Please turn the amplifier to STANDBY before toggling this switch
BIAS TEST
and
COM
multimeter probe jacks – use this for external bias current
measurements (see Section 5, Page 8)
HT FUSE
0.5A SLO BLO fuse – used to protect your amplifier from voltage spikes or
excessive current draw. Replace only when necessary.
MAINS FUSE
SLO BLO fuse – used to protect your amplifier from voltage spikes or
excessive current draw. Replace only when necessary. 3A is used for amplifiers used with
a 120VAC country supply, and 2A is used with 240VAC.
MAINS
IEC cable inlet – plug a suitable IEC power cable into this inlet to power your
amplifier
