The Classic 45 is a compact 10 watt CLASS A/45 watt class AB valve
guitar combo amplifier, which gives a clean, warm and rich sound.
Exceptionally easy to use, combined with the possibility of obtaining a
clean and warm overdriven tube sound at sensible volumes.
The new model has several advantages over its predecessor. Along
with having a line level input for external preamp the Classic 45 has
significantly reduced background noise, especially when used at low
volume. The volume control is smoother and more gradual, also the
circuit uses film capacitors WIMA, and the output valves are of higher
quality. The Power on and off switch is made by the French firm APEM
for more reliability. The amplifier uses valves 2x 12Ax7(2xECC83), 2x
6L6.

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.
