OUTPUT_&_SOLO_CONTROLS:
controls have been set for the desired sound style and the two channels levels have been balanced with the channel MASTER controls,
the OUTPUT control allows you to change the playing level by adjusting a single control. The OUTPUT_control is also wired as the Effects

NOTE: The Effects Loop RETURN jack can serve as a power amp input so that you may use the LONE_STAR_amplifier as a power amp
for either stereo reproduction or to incorporate additional pre-amps. Here are a few things to remember that will help you when interfacing
to the LONE_STAR_for use as a power amp only;
1.)__Connect "Dummy" plug or loose cable to SEND jack. ( This prevents any possible loading that could result in diminished RETURN
sensitivity.)
2.)_ The OUTPUT Level will be the only active control on the Front Panel (the PRESENCE control of Channel 1 will be active only when
that channel is engaged - see #3 )
3.) The SOLO control may be used to footswitch to a pre-determined amount of boost when the footswitch is connected.
NOTE: Therefore, we recommend selecting Channel 1 when you wish to use the LONE_STAR as a power amp.
SOLO:___ T his_control_can_only_be_activated_if_the_correct_Footswitch_is_connected to the Footswitch DIN jack. SOLO is an additional
final output level control wired in parallel with the OUTPUT control. It is capable of a setting above that of the OUTPUT control and can not
be set below. The amount of apparent boost also depends on that of the OUTPUT control - in that if the amplifier is at either the extreme
low or extreme high levels of the OUTPUT, its effectiveness is minimized. It has been optimized for live performance volume levels.
If the power section is either not a part of the sound (super quiet), or producing all its rated wattage (super loud), there is very little signal
for the SOLO_control to work with. By using the Footswitch and selecting SOLO, a pre-settable boost in overall levels is possible on the
fly...giving you some control over your levels when it's time to step out. Engineers may give you a bit of a frown the first time you use it...but
isn't it time you heard yourself. It might even prevent them from punishing you with the dreaded monitor or sidefill version of your tone.
POWER:__TWEED_/_OFF_/_ON
STAR incorporates a built-in VARIAC feature that enables you to reduce the line voltage to approximately 93 volts (with a steady 117 at
the wall). This_TWEED_power setting produces a spongier, scoopier response and allows you to power clip the amplifier at lower overall
volumes. It is especially useful in achieving old school clip sounds in Channel 1 and Channel 2 with the DRIVE
bypassed.
TWEED
ON
These sounds are further enhanced when the TWEED power feature is used in combination with the 50 watt setting
POWER_OFF
and TUBE RECTIFIER:TRACKING is selected. Another bonus is that if you were to use the TWEED power setting
STANDBY
often, tube life would increase substantially.
ON
For maximum power, normal response and the greatest headroom use the ON setting of the AC power switch.
OUTPUT: This control determines the overall output volume level of the amplifier. After the GAIN
Loop Return Level control.
Should you ever use your LONE_STAR_amplifier as a power amp alone by inserting a
SOLO
LOOP ON
signal into the RETURN jack, the OUTPUT control will serve as the master level control.
NOTE: To use the LONE_STAR_amplifier as a power amp - use the EFFECTS RETURN
as an input. The SOLO control can be used to attain a footswitchable boost if the Footswitch
is connected. It is wired in parallel to the OUTPUT control and therefore also controls the
volume of the power section.
This sideways 3 position toggle switch determines the status of the incoming AC power. Your LONE_
