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
m
otion after nun plugging the amp from the mails.
Always install a serviceable valve
