The Nature Of Tubes — Why (And When) To Replace Them:
Tubes are made up of a number of fragile mechanical components that are vacuum-sealed in a
glass envelope or bubble. The tube’s longevity is based on a number of factors which include
how hard and often the amplifier is played, vibration from the speakers, road travel, repeated
set up and tear down, etc.
If your amplifier squeals, makes noise, loses gain, starts to hum, lacks “sensitivity,” or feels as
if it is working against you, then a preamp tube may need to be replaced.
Remember to use
only high quality, low microphonic tubes in the preamplifier section.
Survival Tips For Tube Amplifiers:
To prolong tube life, observe these tips and recommendations:
• 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.
• Allow the amplifier to warm up to room temperature before turning it on. The heat gener-
ated by the tube elements can crack a cold glass housing.
• 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 center before using it.
• Proper maintenance and cleaning in combination with routine checkups by your authorized
service center 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
