Connect your guitar to INPUT using a cable with 6.3 mm (1/4") jack. Set
switch to ON to get the mains power flowing. The amp lights up and the
tubes will begin to heat up. Give the tubes about 30 seconds to get toasty;
then you can set the STANDBY switch on. The amp is ready now. When
taking a short break from playing, please use the STANDBY switch so the
tubes remain at operating temperature. This protects them and ensures they
last longer.
ATTENTION! Do not use the amp when speaker jack is plugged out!

4. TROUBLESHOOTING

5. SPECIFICATIONS
In some cases, you may encounter problems such as noisy valves, howling
and internal valve faults. All valves have a finite lifespan. If problems occur it
may be easily rectified by replacing a valve. A faulty valve may be identified
by knocking the valve body which may exhibit extra noise. But be aware that
some noise when knocking a preamp valve can be a natural phenomenon.
When a pre amp valve (12AX7) fails it should result in continuous
microphonics.
The simplest solution is to replace a faulty valve with a known good one.
Sometimes it is enough just to change valve places.
The faulty valve may be removed when cold by using a gentle circular
motion after nun plugging the amp from the mails.
Always install a serviceable valve.
