TUBE DRIVER AMPS
OWNER’S MANUAL
FRONT PANEL FEATURES (left to right)
TUBE DRIVE SWITCH — Selects either TUBE Channel (up), or CLEAN Channel (down). Red LED indicates Tube chan-
nel is on. Footswitch jack insertion (rear panel) cancels the operation of this switch.
CH. 1 & 2 SWITCH — When this switch is in the "up" position, both channels (Tube and Clean) may be paralleled and
will be heard together when the Tube Drive switch is set to the Tube Drive position (up). With Ch. 1 & 2 switch up and
Tube Drive switch set for Clean channel (down), only the clean channel will be heard. When Ch. 1 & 2 switch is in the
"down" position, the Tube Drive switch will select separately between Tube and Clean channels.
INPUT JACK — Extremely wide -range input allows plenty of headroom for all types of guitars.
TUBE DRIV E — Adjusts the amount of gain that drives the tube. Careful attention has been given to produce the most
overdrive/sustain possible without creating unnecessary noise and feedback.
RED LED — Indicates that the Tube Drive channel has been selected.
TUBE MASTER — Adjusts the amount of output volume from the Tube Drive Channel.
HI, MID, LO — Classic, passive 3-band E.Q. to enha nce the Tube Driver's unique tonal response.
Frequencies: Hi 3.5 KHz (upper shelving)
MID 800 Hz (center)
LO 150 Hz (lower shelving)
CLEAN GAIN — Adjusts gain level of clean channel. Although this channel is all FET, ex tremely warm tubey tonality is
produced thanks to the MosValve power section. Lows are especially well-balanced.
HI, MID, LO — Identical operation and frequencies to Tube Drive channel, however the over-all baseline E.Q. has been
optimized for clean and rhythm styles.
REVERB — Adjusts amount of reverb signal is mixed into the output. Reverb can be cancelled anytime by the footswitch, or by turning the control to "0".
POWER — Supplies mains power to the amp. Be certain that the proper voltage is supplied to the amp. The proper voltage for your unit is indicated just below the fuse holder on the rear panel.
REAR PANEL FEATURES (left to right)
POWER INPUT CORD — Heavy -duty cord supplied to the requirements of your local. In USA: Conn ect only to 110-120
VAC, 60 Hz. Always use grounded outlet (3 terminal) to avoid operating problems and to increase safety margin.
FUSE — Use fast-blo 4 Amp for 120 VAC or 2 Amp for 220 -240 VAC models. Always replace with the same type and
size fuse.
SPEAKERS — Connect only to speakers. Either 2 - 8 ohm or 1 - 4 ohm speaker or cabinet combination. Combo amps:
The speaker supplied is 8 ohm, enabling you to add one more extension 8 ohm speaker without damaging the amp.
Minimum total impedance is 4 ohms. Lower impedance operation may eventually overheat and damage the amp voiding
warranty. Any questions; please consult a qualified person, or call us at the factory.
LINE OUT — Attenuated signal from the output of the amp. All the tone of the amp, including the output is available at
this jack. Potential applications: Slaving to other combo or power amplifiers and recording.
FOOTSWITCH — Stereo-type jack which switches both Channel and Reverb. Tip of the jack is Reverb; ring is Channel.
Note: Electronic and MIDI switchers - Channel switch is VC positive to ground. Reverb is simple shorting.
EFFECTS SEND — Proper send level for most effects devices. Connects to the "in" or "guitar” jack of your effects. Can
also be used as a D.I. (Direct Input) to a mixing console or recorder.
EFFECTS RECEIVE — Unity buffered input from effects devices. Connects to the “out” or "amp" jack of your effects.
Can also be used as a direct Power Amp section input. NOTE: A common problem many encounter while using effects
devices is "ground loops". A ground loop is often caused when an effects device, mixing board or tape recorder
equipped with a 3-prong AC cord are connected together with audio cables. The electrical difference between the AC
ground (at the AC plug) and the signal ground (audio cords) is amplified. This may result in increased hum levels and in
some cases high -pitched squeals or oscillation at high gain settings of the amp. The solution is often to use the same
outlet strip fo r all equipment rather than plugging into various separate outlets. In extreme cases it may be necessary to
isolate the AC grounds. If this is attempted, consult a qualified technician to insure safety. Tube Works cannot recommend the disabling of any 3rd prong grounding plugs.
