STEP A:MakesurethatyourampisOFF.PlugitintotheVariac.TheVariacisOFFwiththeoutputvoltage
knobsettozero(0).TurnontheVariac’spower.Then,turnontheamp’spower.
Variac:AvariabletransformerusedtovaryACvoltages.Also
thetradenameforabrandofvariableACtransformer.There
areotherbrands,butthetermisgenericallyusedtodescribe
allofthem.Avariacallowsadjustmentoftheincoming
ACmainsvoltage.Thebetterqualityunitshavemeters
forvoltageandcurrent,orboth,andfusesforprotection.
Variacscomeinmanyshapesandsizes.Buttheirfunctionis
basicallythesame.Ifyourvariacdoesnothaveanamperes
(current)meter,you’llneedtouseaseparatemeter.
NOTE:TheVariacinthephotototheleftdoesnothavean
amperesmeterwhereastheTenmamodeldoes.
