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!
OUTPUT SELECTOR
three-way rotary selector. Set to the position that matches the impedance of your speaker cabinet.
NOTE
– if you are using two speaker cabinets in parallel (ex – two 16 Ohm cabinets), set the impedance selector to half that of
a single cabinet (in this case, 8 Ohms).
BIAS TEST
multimeter probe jacks – use this for external bias current measurements (see Section 5)
PENTODE / TRIODE
switch – allows user to further control the power and response of the amplifier. In 100W position, the
power section is in pentode operation, and provides greatest headroom and dynamics. In 50W position, the power section is in
triode operation. This not only reduces output power, but compresses attack, softens high frequency transients, and provides a
softer attack.
MAINS
IEC cable inlet – plug a suitable IEC power cable into this inlet to power your amplifier
MAINS FUSE
slow-blow 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.
HT FUSE
T500mA fuse – used to protect your amplifier from voltage spikes or excessive current draw. Replace only when
necessary.
