[Amps] Alpha 76 "SNAP" noise

[John G3UUT]

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.

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!
