1.) After unpacking the amplifier remove the plastic webbing from all of the tubes (including the preamp tubes behind the row of
power and rectifier tubes) and make sure all tubes are seated firmly in their sockets.
2.) Install the 5U4 Rectifier tubes (if they are not already in place) by bending back the spring steel tube clamps just enough so that
the base of the tube will have to barely push the clamps out of the way as they go in. Be sure to line up the guide with the slot in
the socket, don’t force it…when it is lined up it will fit in the socket easily. When the tube is lined up gently press the tube into the
socket while rocking it back and forth until it is seated.
3.) Connect the 8 Pin DIN Footcontroller Cable to the female DIN connector located on the Rear Panel just under the Rotary Mode
Select Switch.
4.) Connect the A.C. Power Cable to a grounded A.C. outlet.
5.) Flip the A.C. Mains switch to the BOLD position and wait at least 30 seconds for the power tube filaments to warm up with the
STANDBY switch in the down (STANDBY) position. This cold start procedure prolongs tube life so try to follow it each time you
power up the amplifier.
6.) Turn the Front Panel OUTPUT control to zero before flipping the STANDBY switch to the ON position. This will prevent accidental
settings that are too loud for the room and your ears. These amplifiers are LOUD and are capable of extreme volumes and should
be used with care to avoid damage to your hearing. Starting each power up with the OUTPUT control zero-ed help to eliminate
painful and/or embarrassing situations.
7.) Flip the STANDBY to the ON position and enjoy your new instrument.
1.) The Rear Panel CHANNEL SELECT Rotary switch must be set to FOOTSWITCH to access either Channels or features via the
footcontroller.
2.) The OUTPUT and SOLO controls work only if the Effects Loop is active. Switch out of the LOOP BYPASS position in the
EFFECTS LOOP section of the Rear Panel.
3.) The SOLO Control is activated when the Footcontroller is connected to the FOOTSWITCH jack on the Rear Panel and the Ef-
fects Loop is taken out of LOOP BYPASS and activated. When the Footcontroller is not connected the SOLO control will have
no effect on the signal.
4.) The SOLO feature can be used to set a volume level above that of the OUTPUT control setting. It will not allow a setting below
that of the OUTPUT control.
5.) The GAIN and TREBLE controls are the most powerful controls in all four channels. They should be used with taste and you will
find that many of the best sounds are found with the controls set somewhere in their middle regions. Avoid setting the TREBLE
above 2:00 when the GAIN is maxed as the possibility of unwanted noise and squealing from microphonic tubes increases
dramatically above this setting.
6.) You will notice a substantial volume increase when switching from either the RAW or VINTAGE modes to the MODERN mode
in Channels 3 & 4.When switching modes Always check your MASTER controls to avoid sudden volume increases. It is a good
practice when setting up your channels, to get in the habit of zeroing out the Channel MASTER control each time you switch
modes.
