Page 8: Important.information.about.tubes.and.tube.products
Important Information about Tubes and Tube Products: 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. Any.time.you.notice.a.change.in.your.amplifier’s.performance,.check.the.tubes.first. If.it’s.been.a.while.since.the.tubes.were.replaced.and.the.sound.from.your.amplifier.lacks. punch,.fades.in.and.out,.loses.highs.or.lows.or.produces.unusual.sounds,.the.power.tubes. probably.need.to.be.replaced..If.your.amplifier.squeals,.makes.noise,.loses.gain,.starts.to. hum,.lacks.“sensitivity”,.or.feels.as.if.it.is.working.against.you,.the.preamplifier.tubes.may. need.to.be.replaced. The.power.tubes.are.subjected.to.considerably.more.stress.than.the.preamplifier.tubes.. Consequently,.they.almost.always.fail/degrade.first..If.deteriorating.power.tubes.aren’t. replaced.they.will.ultimately.fail..Depending.on.the.failure.mode,.they.may.even.cause.severe. damage.to.the.audio.output.transformer.and/or.other.components.in.the.amplifier..Replacing. the.tubes.before.they.fail.completely.has.the.potential.to.save.you.time,.money.and.unwanted. trouble..Since.power.tubes.work.together.in.an.amplifier,.it.is.crucial.that.they.(if.there.is.more. than.one).be.replaced.by.a.matched.set..If.you’re.on.the.road.a.lot,.we.recommend.that.you. carry.a.spare.matched.set.of.replacement.power.tubes.and.their.associated.driver.tubes. After.turning.off.the.power.and.disconnecting.the.amplifier.from.the.power.source,.carefully. check.the.tubes.(in.bright.light).for.cracks.or.white.spots.inside.the.glass.or.any.other.appar- ent.damage..Then,.with.the.power.on,.view.the.tubes.in.a.dark.room..Look.for.preamplifier. tubes.that.do.not.glow.at.all.or.power.tubes.that.glow.excessively.red. Whenever.you.replace.the.power.tube(s): •. - Page 9 Important Information About Tubes and Tube Products (continued): The Importance Of Proper Biasing: For.the.best.performance.and.longest.tube.life,.proper.biasing.is.imperative..Bias.is.the.nega- tive.voltage.which.is.applied.to.the.power.tube’s.control.grid.to.set.the.level.of.idle.current.. We.cannot.over.emphasize.the.difference.in.warmth.of.tone.and.dynamic.response.that.come. with.proper.biasing..If.the.bias.is.set.too.high.(over.biased),.the.sound.from.the.amp.will.be. distorted.at.all.levels..If.the.bias.is.set.too.low,.(under.biased).the.power.tubes.will.run.hot.(the. plates.inside.the.tubes.may.glow.red.due.to.excessive.heat).and.the.sound.from.the.amplifier. will.lack.power.and.punch..The.excessive.heat.greatly.reduces.tube.life.–.from.a.few.days.to. as.little.as.a.few.hours.in.extreme.cases..Setting.the.bias.on.your.amp.is.like.setting.the.idle. on.your.car..If.it’s.too.high.or.hot.it’s.running.away.with.you.and.if.it’s.too.low.or.cold.it.will. choke.when.you.step.on.it. The.bias.is.adjusted.at.the.factory.in.accordance.with.the.type.of.power.tube(s).installed.in. your.amplifier..It.is.important.to.point.out.that.tubes.of.the.same.type.and.specification.typi- cally.exhibit.different.performance.characteristics..Consequently,.whenever.power.tubes.are. replaced,.the.bias.voltage.must.be.checked.(unless.the.amplifier.is.equipped.with.“self-biasing”. circuitry).and.readjusted.to.accommodate.the.operating.parameters.of.the.replacement.tubes. Depending.on.the.model.and.amplifier.type,.there.may.be.hum.balance.controls,.trim.pots,.or. bias.adjustment.controls.on.its.rear.panel..However,.the.bias.adjustment.should.be.performed. only.by.qualified.service.personnel.with.the.proper,.calibrated.test.equipment.
- Page 10 Important Information About Tubes and Tube Products (continued): Survival Tips For Tube Amplifiers: To.prolong.tube.life,.observe.these.tips.and.recommendations: •. 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. •. 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.gener- ated.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.a.power.tube.breaks.off,.replace.the.tube..This.signifi- cantly.reduces.the.risk.of.damaging.your.amplifier.by.incorrectly.inserting.the.tube. •.
