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.

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.
