Survival Tips for Tube Amplifiers:
To prolong tube life, observe these tips and recommendations:
•
Make sure the speaker(s) are properly connected prior to turning on the amplifier. DO NOT
OPERATE THE AMPLIFIER WITHOUT A SPEAKER OR PROPER DUMMY LOAD ATTACHED. TO DO
SO WILL DAMAGE THE AMPLIFIER.
•
Allow the amplifier to warm up to room temperature before turning it on. The heat generated
by the tube elements can crack the cold glass housing.
•
After playing the amplifier, allow sufficient time for it to properly cool down prior to moving it.
A properly cooled amplifier prolongs tube life due to the internal components being less
susceptible to the damage caused by vibration.
•
Match the impedance of your speaker cabinet(s) to your amplifier. Improper impedance
matching will contribute to early tube degradation and may cause premature tube failure.
•
Replace the output tube(s) before the performance degrades or the tubes fail completely.
Check the tube(s) when you notice degraded performance.
•
If the locating notch on the base of a power tube breaks off, replace the tube. This significantly
reduces the risk of damaging your amplifier by incorrectly inserting the tube.
•
Protect the amplifier from dust and moisture. If liquid gets into the amplifier proper, or if the
amplifier is dropped or otherwise mechanically abused, have it checked out at an authorized
service technician before using it.
•
Proper maintenance and cleaning in combination with routine checkups by an authorized
technician will insure the best performance and longest life from your amplifier.
CAUTION
: Tube replacement should be performed only by qualified service personnel who are familiar
with the dangers of hazardous voltages that are typically present in tube circuitry.
