[R-390] caps redux

[Johnsay Johnsay]

Hi all.
I guess I stirred up a bee hive with my original question about caps.
What I was hoping to resolve is the suitability of metalized film caps for replacement use in this equipment.
There has been a lot of useful information posted but I haven't seen any data that would actually correlate their use with field failures.  Reviewing the archives (pearls?) I know they have been used in quite a few cases and they do have their adherents.  
So what I take away from this, is that I'll use film foil for C553 and C275 (I don't want to have to pull the RF deck out again any time soon).  I'll use the Panasonic PP metalized films that I have in stock for the rest.  Those would be easier to replace.  Interestingly I noticed that R525 had been very crudely replaced, probably while in govt. service due to a failure of  BB C539.  
Thanks all....  John, W8KX
