the worst was the acrid smoke like mustard gas has us gagging, the fireworks was pretty scarry too. if i were to test a unit, id do it outdoors on concrete. my unit burnt the wood floor under it and could have caused a fire. the box was extreamly hot, you couldnt toutch it.
my unit was in use for years, it just gave out one day without warning.
yeah the amperage draw is high. when id turn it on, the loft would brown out for a second or two till it cycled... it was on a 20 amp breaker that didnt trip right away either. realize the caps are fully charged n hold it for quite awhile. im sure a shock will be deadly... i wouldnt toutch the box when it blew just incase it was shorted to the metal case.
i know people that reshape caps by slow charging. but a marginal cap may work fine for awhile but is it worth taking a chance burning down the house? id trash the old units. the newer strobes are so much better n faster.
