Sorry folks, are we talking about the string of smoothing electrolytics
or a ceramic RF filter cap here? I'm curious about this as when I
switched my 2m amp on recently which hadn't been used for about a year
there was a regular series of 'snaps', the frequency of which gradually
diminished as it warmed up. I was worried by this but it didn't seem
catastrophic and seemed to be improving with time so I left the amp on.
By the end of the contest the amp was usable (typical) - I couldn't
really use it earlier as the snaps put quite a high level pulse of QRM
into the RX path.

Oh yes. I heard this coming from one of our old Alpha 78s during CQWW CW at
5U5Z some years ago. It did this for quite a few hours and then in the middle
of the night there was a big bang and the room filled with smoke as one of the
filter caps let go. It certainly woke the operators up. I should change those
caps now!
