Not sure why it happeped--but my colorvolt just DIED !!

it was running my Panasonic LCD projo--with an UNDER 200 watt load. Everything seemed fine and THEN--that thermal relay begin to chatter--and the set went off.

At first--I though the transformer had shorted--but that did NOT make sense, since it had NOT smoked or such. But now--it would nOT hold a load--and hummed quite loud and clicked off and on. SO then--i figured the thermal relay had died. This is somehow used to sense when a load is connected and then "shunts" in the ferro tranny. So--I tried to bypass it and the tranny hummed load but NO output. I really felt my tranny had died.

then--I looked at the diagram of this thing--in the Electronics world magazxine from 1970, Feburary. SOMETHING seemed to be dragging down the output. The oil capacitor maybe--YES. For some reason--it is now SHORTED. It is a 5UF 660v cap, from what the diagram in EW says.

NOW_-do I REALLY need a 660 volt cap--I do NOT think the kick voltage from the tranny would get that much over 300 volts--would it--I can get a 5uf 450 or so volt cap easily.
