[BC] exciter problem fix of note

[Michael Patton]

Yesterday I was going through a BE FX-30 on my bench and noted spurious 
emissions at +/- 30 KHz and +/- 60 KHz, about -50 dBc.  Checking the 
output of the mod osc by itself, I found no spurs.  Hey, I know this 
one: the electrolytic P/S bypass caps in the PA are dead.  I 
disassembled the PA module and changed the caps, using 105° caps instead 
of the original 85° caps (shame on you, BE), and hey, presto! no more spurs.

So far, so good.  Here's the interesting part:  just for kicks, I tested 
the old caps on a cap checker, and they showed full value!

So let this be a learning experience, that some electrolytic caps are no 
longer fit for duty even tho they test OK.

Have any others out there had similar experiences, where caps tested 
good but misbehaved in circuit?
