ThisprojectanditsdocumentationistheresultoftechnicalinvestigationsmadebytheengineeringstaffofMercury Magnetics.Thedisclosureoftheinformationhereinmaypertaintoproprietaryrightsand

yellowandmaybeputapieceofshinytapeon
ittomakeitmorevisible.Youcanevenputa
fuseinserieswiththeresistoronthedischarge
toolincaseyouforgettoremoveit.
Filtercapacitorsarewiredinparallel,sodraining
oneshoulddrainthemall,butneverassume.
Alwaysrecheckforresidualvoltageineverylter
capacitoruntilthere’sabsolutelynodoubtinyour
mindthatallaredrained.
Lessthan5voltsissafe,butIprefertodrainmine
to1voltforpeaceofmind.Don’tbesurprisedifyou
ndthecapacitorsslowlyrechargingthemselves.
Thisphenomenonisknownasdielectricabsorption
andisquitenormalinelectrolyticcapacitors.The
ltercapsshouldn’trechargetoalethallevel,but
leavethedischargetoolinplacewhileworkingon
theamp.
Afewnalnotes:
1. Neverworkonanampifyou’retired,fatigued,
frustratedorintoxicated.
2. Neverworkwhiledistracted.
3. Neverworkonanamparoundsmallchildren.
Therearejusttoomanydangersinvolvedto
takethatchance.
4. Trytohaveaplanincasesomethingdoesgo
wrong.Youmightconsideraskingsomeonein
yourhouseholdtotakeaCPRclass.
5. Takeyourtimeanddon’trush.
6. Usecommonsense.
