[Amps] Mica cap substitute \ alternative

[Tom W8JI]

 So we are  told that some manufacturers derate some mica 
caps above 5MHz. Others have caps that in slightly different 
applications have ratings that are high. Some mica caps can 
handle high currents in the VHF range. Dissipation factor 
wouldn't, prima facie. seem to be the critical parameter 
between all these products.

Here's something I noticed about technical questions or 
topics.  If someone gives a simple authoritative answer that 
everyone can just accept on the surface without having to 
understand the actual problem, it gets accepted. That seems 
to be true even when the answer is so grossly oversimplified 
it winds up being wrong in the big picture.

I think it is rooted in wanted an answer without learning 
how something really works.
