Silver button mica ?
 

I've got a TMC Directional Coupler Unit Model CU 2/50 and my "cheatsheet"
for silver button micas is not to be found. I wonder if someone has one and
can tell me the capacitance of one that has the following six colors: black,
brown, red, green, gold, grey. If anyone has a schematic, please let me
know.
tnx
