REAR PANEL FEATURES
(left to right)
POWER INPUT CORD
— Heavy -duty cord supplied to the requirements of your local. In USA: Connect 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 enc ounter 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 for 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 recom-
mend the disabling of any 3rd prong grounding plugs.
