18 The line power switch is of the three position
type with the center position being off. The three posi-
ton switch has two ON positions, one of which is used
to ground the amplifier properly. One of the ON
positions will yield the least hum or popping when the
instrument is touched and this is the position that should
be used
For your safety, we have incorporated a 3 wire line
(mains) cable with a grounding lug. It is not advisable to
remove the ground pin under any circumstances. If it is
necessary to use the amp with the old two prong
sockets, a suitable adaptor should be used. Much less
noise and greatly reduced shock hazard exists when
the amp is operated with the proper grounded recep-
tacle.
19 The Standby Switch removes the B+ supply
from the output tubes while leaving the filament voltage
on. This function keeps the tubes at operating
temperature and allows for instant operation when the
Standby switch is thrown.
20 The main speaker output Jack is where the
main speaker must be plugged in. The output in-
pedance of this jack is 4 ohms.
21 The external speaker Jack is designed to allow
use of an additional speaker system with the Deuce.
This jack does not become operational until the main
jack has been connected to a speaker. Due to a special
switching jack which connects a separate 2 ohm tap on
the output transformer, a 4 ohm load may also be con-
nected into this jack—thus allowing the amp to put out
full power into a total impedance of 2 ohms when an ex-
tension speaker is desired. The output impedance of
the Deuce is 4 ohms when the main speaker jack is
used and 2 ohms when both are used. NOTE: No less
than a 4 ohm speaker system should ever be con-
nected to either speaker jack.
22 A “Din” Socket is located on the back panel for
the Automix footswitch. Care should be taken to proper-
ly mate the connectors of the footswitch plug with the
respective socket holes.

FOOTSWITCH
Selector Button
As the name implies, the selector button allows
you to select between the normal and bright channels.
This button is functional with your instrument plugged
into either the series or parallel input
Combiner Button
The combiner button deactivates the selector
button and allows both channels to be in the circuit at
one time. The selector button becomes inoperative as
soon as the combiner button is depressed.
Reverb Button
The reverb button activates reverb on both
channels.
Tremolo Button
The tremolo button activates tremolo on the
effects channel
NEVER OPERATE THE AMPLIFIER WITHOUT A
SPEAKER LOAD!! This amp is equipped with a shorting
system on the main output jack to help protect against
accidentally turning on the amp without a load. If ihe
speaker patch cord is plugged into the amp, bul not
connected to the speakers, the amp is NOT loaded and
could cause problems if the amp is turned on and
Operated in this manner. The natural inductance of the
output transformer can store energy that normally is
transferred to the speaker and is capable of developing
tremendous voltages. These voltages can cause serious
internal arcing between the elements of the output tubes
and their related circuitry.
The 6L6GC output tubes are the most rugged audio
power tubes on the market and should provide long ser-
vice in the output circuit. Each tube has a keying pin
moulded into the base to index the pins into their proper
positions. When installing or removing the tubes, it is
possible to break Off these index pins by bending the
tube too much in its socket. Use extreme caution when
handling the tubes. UNDER NO CIRCUMSTANCES
SHOULD TUBES WITH BROKEN OR MISSING INDEX
PINS BE INSERTED IN THE SOCKETS.
