I just got a TMC Directional Coupler Unit Model CU 2/50 and wonder if anyone
would have specs or a schematic? Inside it has a 0.6 ohm 40 watt resistor
inline with input and ouput. Off each end of this resistor it has a silver
button mica capacitor. My "cheatsheet" for silver button micas is not to be
found. I wonder if someone can tell me the capacitance of a silver button
mica that has the following six colors: black, brown, red, green, gold,
grey.

Hi Hank,

Practical issues like this are often deferred while angel population
counts on pin-heads are being conducted. ;-)

There are two styles of marking these components. One occupies half
the arc of the button, the other occupies 240 degrees of the arc.

Given that you start with the color black, I would presume this is of
the first variety. As such: 1,2, X100000, 5%, 6 GOhms resistance.

I remember when all Hams had to pass an examination that included how to
read the color codes on resistors and capacitors.

Sigh! But that was back in the good ol' days ... sigh ...

When resistors and capacitors had color codes. Ever see a color code
on an SMD device? :-)

Yes. 6 of them, minimum. That's what the grey stands for. This
color is non-standard for button types (complete with non-standard
spelling) and refers to standard Mica. However, even for button types
there's a minimum of 7.5 GOhms to as high as 50 GOhms possible.
