Hi Tony.
Using disc ceramics in the output of a PA is not adviceable. First, they
MUST be C0G or NP0. And even very short leads are negative. So I´ll
strongly advice to use only ceramic NP0 SMD capacitors with >500V ratings.
So far, I have not had any problems with the Munin PA´s I have built and
used.
But I wrongly stated 200V rating for them in the original BOM. Sorry for
that!
Season greetings to all of the Munin builders and the rest of the
OpenHPSDR followers!
73, Kjell
