Question about Magnavox 4 lead safety cap 250663-19

[radiotvnut]

Howdy,
I have a 19" touch tune Magnavox set that uses a T809 chassis with that pesky grey safety cap that shorts. I found a very used cap in my junk that got the set playing for a couple of hours. Then, that one shorted. I've looked in all my TV parts catalogs for this part without success. I've heard that these Magnavox caps were unreliable and are a common problem. I was wondering if anyone has had any luck replacing this four leg cap with something more reliable that is easier to obtain. The part number is 250663-19 and the value is: .0195 uF, 1.2kv, 5%. The cap is connected from the HOT collector to ground. This set had a nice picture when I had it going and I'd like to keep it as a spare TV (at least until a 4-tube hybrid Zenith comes along).

Thanks for your help.
