18. INDICATOR LAMP- This lamp will illuminate when the power switch is in
the “up” position, indicating the unit is receiving A/C power.
NOTE: All switches are ON in the “up” position.
REAR PANEL FUNCTIONS
1. A/C INPUT- Connects the amplifier to A/C power via the power cord
supplied. Unless otherwise specified, your amplifier is designed to operate
on 120 volts A/C, 60 cycles.
2. FUSE- 3 AG Type, slow blow fuse. Refer to the legend below the fuse holder
for the proper fuse rating for your amplifier. (50 watt-2.5 amp /100 watt-
3.5 amp)
3. POWER SWITCH- Turns the power on.
4. CLASS A-A/B SWITCH- This function switch changes the POWER SECTION
from CLASS A to CLASS A/B mode.
CAUTION!
You must reset the bias current when you change output tubes
for Class A/B operation! In cathode bias mode(class A), you may insert any
matched pair of 6L6, EL34, 6V6, or 5881 without rebiasing in the amp. You
may also operate the amp in high or low power mode. In class A/B, be sure
the tubes used are matched, and the correct bias current is used.
FAILURE TO DO SO MAY DAMAGE THE TUBES, THE AMPLIFIER, OR
BOTH!
5 FOOTSWITCH JACK- Connect the foot switch assembly here to enable
remote switching of the lead/rhythm and bypass functions
6. SPEAKER OUTPUT JACKS- There are 3 speaker output jacks- 4,8 and 16 ohm.
NEVER OPERATE YOUR AMPLIFIER WITHOUT A PROPER SPEAKER
LOAD CONNECTED.
Be sure to match the impedance of your cabinet with
the impedance (output) of the amplifier.
