4. TROUBLESHOOTING45. SPECIFICATIONSIn some cases, you may encounter problems such as noisy valves, howlingand internal valve faults. All valves have a finite lifespan. If problems occur itmay be easily rectified by replacing a valve. A faulty valve may be identifiedby knocking the valve body which may exhibit extra noise. But be aware thatsome noise when knocking a preamp valve can be a natural phenomenon.When a pre amp valve (12AX7) fails it should result in continuousmicrophonics.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 circularmotion after nun plugging the amp from the mails.Always install a serviceable valve.6.
