Can the transformer on a stinger bug zapper be replaced?

Yes--the transformer can be replaced--However, as far as I can learn, the replacement part is only available thru the manufacturer, and the part would cost almost as much as a new, complete bug zapper--SO-O-O-O---it would seem that these are basically a "disposable" item--if anything goes wrong with it, other than the bulb--it's gonna be best to just toss it and get a new one--cost is about $45.00 on some very good models--mine was the 1-acre of coverage model, and that thing ran for days in "ON" mode, and lasted for years--
