Survival Tips for Tube Amplifiers

To prolong tube life, observe these tips and recommendations:

 •Matchtheimpedanceofthespeakercabinet(s)totheamplifier.Improperimpedancematching 

will contribute to early tube degradation and may cause premature tube failure.

 •Makesurethespeaker(s)areproperlyconnectedpriortoturningontheamplifier. 

 •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generatedby 

the tube elements can crack a cold glass housing.

 •Replacetheoutputtube(s)beforetheperformancedegradesorthetubesfailcompletely. 

Replace the tube(s) on a regular basis; at least once per year or as often as every 4 to 6

months if you play long and hard every day.

 •Alwayshavethebiascheckedafterreplacingtheoutputtubes(unlesstheamplifierisequipped 

with “self-biasing circuitry”). This should be done ONLY at a qualified service center. Improper

biasing could result in the tubes running too hot, which greatly reduces the life of the tubes – or

too cold, which results in distorted sound regardless of level settings. Do not play the amplifier

if it exhibits these symptoms – get the bias checked/adjusted immediately to prevent tube failure

and/or other damage.

 •Ifthelocatingnotchonthebaseofthepowertubebreaksoff,replacethetube.Thissignificantly 

reduces the risk of damaging the 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 center before using it.

 •Propermaintenanceandcleaning–incombinationwithroutinecheckupsbyanauthorized 

service center – will ensure the best performance and longest life from the amplifier.

CAUTION: Tube replacements should be performed only by qualified service personnel who are

familiar with the dangers of hazardous voltages that are typically present in tube circuitry.
