THE CONTROLS
1. INPUT Hi & Lo.
High impedance input is for instruments without a built in amplifier or high output
Coil type pickups.
Input Hi provides more gain than the Lo input Both Hi and Low inputs can be used
It is not essential to use one type use to your own taste.
2. VOLUME.
Adjusts the gain of the pre-amp and is used in conjunction with the
MASTER control to set the overall volume of the amplifier.
3. BASS.
Adjusts the amount of low frequency boost.
4. TREBLE.
Adjusts the amount of high frequency, the pull switch lowers the frequency.
5. MIDDLE.
Adjusts the amount of mid frequency boost.
6. MASTER
Controls the signal going to the output stage and is after the return loop so will
Adjust any effect output level.
7. MAINS.
When illuminated the valve heaters are on and there is power to the amplifier.
8. STANDBY.
When operated cuts the HT voltage to the amplifier.
9 4 & 8 ohms output
Out-put speaker impedance.
If you have a CORNELL Extension Speaker cabinet set this switch to 4 Ohms.
10 Send / Return FX Loop
Connect the send output to the input on the pedal of the effects unit, the send signal
Is controlled by the volume control. Connect the Return socket to the output of the
pedal or effects unit this is controlled by the Master Control.
MAINS SWITCH operation.
Do not operate mains switch without a 30 second delay between operations.
There is an internal thermistor to reduce mains surges. This thermistor works by
introducing a resistance when switched on, after a few Seconds the thermistor is
heated and the resistance is reduced. When switched off it then takes a few
seconds to cool and retain its resistance before the nexed switch on.
Mains and HT Fuse
The fuse holders contains the mains and HT fuse to the amplifier and
protects the amplifier from electrical faults.
Replace a failed fuse only with the same type and rating.
