[ARC5] Mica Capacitor

[Richard Knoppow]

    BTW, this brings up a question: does anyone know what happened to 
either Micamold or Solar?  Both were well established companies but seem 
to have disappeared around 1947. All advertising stopped and the 
reserved space in the "Radio's Master" had skipped page numbers.  I 
suppose the trade journals must have had something but going through 
them would be very time consuming. There are quite a few on 
Americanradiohistory.com   Both made other kinds of capacitors than the 
flat paper ones.  I was tipped about Micamold by my mentor, an 
electronic designer, probably in the late 1950s.  I had not seen any in 
years but when I got my RCA AR-88 it had several in places that the 
handbook said were mica caps. All were bad.
