I had one of those triple section 0.22 mfd job short out while I was using a receiver. As you 
say, bogged the dynamotor down like mad. Lucky I was right beside it when this happened.

I completely agree with you on this one. By now ALL of those things are leaking or shorted.

If one wants to have his receiver remain completely stock, then put it on a shelf and look at 
it. 

If one wants to have his receiver LOOK completely stock, yet wants to USE it, then restuff 
them. 

Otherwise replace every darned one of them with modern caps, before something 
irreplaceable burns up.
