FUSE
- Replace only with a 2.0 Amp slo-blo fuse. Never install a larger fuse
than specified. Have the
amplifier tested by a qualified technician if it repeatedly blows fuses.
Rectifier Selection Switch
- Your amplifier is capable of using a tube or solid state rectifier. Each
type will yield a slightly different tone. Make sure the amplifier is in standby before changing the
position of this switch.
Power Level
- The power level control is a variable voltage control for the amplifier. At 100% the
amplifier will produce the maximum output and be the loudest. Turning this control
counterclockwise will reduce the overall volume.
Impedance Selector
- Use the Impedance Selector to match the amplifier output impedance to the
attached speaker. The amplifier is capable of handling a 4, 8, or 16 ohm load.
MAIN SPEAKER
- Connection for the primary speaker (internal or
external).
EXTERNAL SPEAKER
- Use this connection when using more than one speaker cabinet.
Note - Do not exceed a 4 ohm load.
