SVT CLASSIC Changing the Tubes The performance characteristics of tubes are degraded in direct proportion to how often and under what conditions the amplifier is used. Power tubes should be checked at least once a year - more frequently if you use the amplifier nearly every day. When power tubes wear out, the amplifier will begin to grow weak, lack punch, fade up and down, or lose highs and lows.
SVT CLASSIC Troubleshooting Troubleshooting Diagram: In the event that your SVT CLASSIC should stop working properly, or just stop working, take a few minutes to troubleshoot it before you call for service. You can save yourself a lot of time and sometimes money doing it yourself, and often the problem is something quite simple. Please refer to the Troubleshoointg Diagram for guidelines. If you think the problem may be worn out tubes, see page 7 for symptoms of tube failure.
