HOT/COOL Switch
When.set.to.COOL.the.TOP.BOOST.channel.operates.in.traditional.fashion.with.the.TREBLE.and.BASS.
controls.fully.activated..When.set.to.HOT,.the.tone.controls.are.partially.bypassed.providing.a.more.pure.
signal.path,.and.a.boost.in.gain..This.feature.is.also.foot.switchable.making.it.perfect.for.boosting.leads.
and.solos!
NOTE!. When.in.HOT.mode.the.tone.controls.still.affect.the.sound.slightly.
MASTER
9.
TONE CUT Control
This.circuit.is.placed.in.the.power.amp.as.opposed.to.the.pre-amp.section.like.the.TREBLE.and.BASS.
controls..What.this.does.is.the.opposite.of.what.you.may.expect..Turning.it.clockwise.will.decrease.the.
higher.frequencies..Use.in.conjunction.with.the.TREBLE.control.to.fine.tune.the.high.end.of.your.sound.
10. VOLUME Control
This.controls.the.overall.or.MASTER.VOLUME.of.your.amplifier..Use.in.conjunction.with.the.NORMAL.
and.TOP.BOOST.volume.controls.to.find.the.perfect.balance.between.pre/power.amp.distortion.and.out-
put.volume.
11. MV/BYPASS switch
This.switch.allows.you.to.completely.remove.the.MASTER.VOLUME.control.from.the.circuit..Giving.the.
tonal.purist.what.they.would.expect.from.a.vintage.AC,.but.also.allowing.for.lower.volumes.if.needed.
OUTPUT Section
12. OP MODE Switch
This.controls.the.output.level.of.the.power.amplifier..When.set.to.half.power.mode.(15W.AC30HW.and.7.5W.
AC15HW).the.power.amp.distorts.less.and.has.a.smooth.high.frequency.roll.off..When.set.to.full.power.
mode.(30W.AC30HW.and.15W.AC15HW).the.power.amplifier.breaks.up.at.higher.volumes.and.produces.
a.more.harmonically.dense.sound.
13. POWER Switch
This.is.the.ON/OFF.switch.for.the.amplifier..Please.ensure.the.amplifier.is.switched.off.and.unplugged.be-
fore.being.moved.

POWER OUTPUT jacks
This.is.where.you.can.hook.up.an.extension.or.external.speaker.cabinet(s).if.desired.

EXTENSION SP:.This.speaker.jack.runs.in.parallel.with.the.internal.speaker.which.is.16.Ohms..The.ex-
tension.cabinet.must.be.16.Ohms.and.the.IMPEDANCE.switch.should.be.set.to.8.ohms.
