I don't think much of the idea of shotgun-replacing these particular caps. There are a great many of them, they're not *that* unreliable, and unlike the notorious radial-lead tantalums, they tend to fail open, not shorted, so they're unlikely to damage other parts when they fail.
On the other hand there are definite risks, from ESD to human error, associated with unsoldering and resoldering a bunch of parts unnecessarily. Just be prepared to open it up once every couple of years to track down the next one. Nothing to be afraid of inside the 8566s. You could rebuild the whole thing from scratch with HP's docs, if you had to. -- john, KE5FX > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] > Behalf Of Jeff Mock > Sent: Thursday, December 06, 2007 7:55 PM > To: Discussion of precise time and frequency measurement > Subject: Re: [time-nuts] HP 8566B repair > > > Thanks so much, that's just the encouragement I need to crack open the > RF section.
