MOTM

Okay, now I'm counting the parts out for the VCA/Ring Mod, and by the
process of elimantion, I think I know which parts are which. But I want to
make sure (you know what they say happens when you 'assume').

Are box caps marked "*470 nk 63" and "D474 J*" both 0.47mfd caps?

Thanks in advace.

And a rhetorical question--why is "violet" specified in the resistor color
code when they always use lavender to mark the parts?

Yep. Again mixing up of the US suppliers (474) and the Europena (470n)

Get used to this, it ain't gonna get better.

  Yes.  470n = 470 x 10^-9 = 0.470 x 10^-6

        474 = 47 x 10^4 x 10^-12 = 47 x 10^-8 = 0.470 x 10^-6

  Resistor part colors tend to vary for specific colors.  Sometimes I
think the factory personnel who program the marking machines try to play
mind games and create colors that are amazingly difficult to discern, such
as reddish-brown.

  As far as the color scale goes, it they were orignally taken from the
"pure" color scale of chromatic light frequencies: red, orange, yellow,
green, blue, indigo, violet.  The common mnemonic taught every astronomer
is "Roy G. Biv".  Now, true violet might be tough to tell from black,
brown or blue on a resistor, thus they lighten it up a bit.  Personally I
think they can afford to print the actual value on resistors anymore; they
got rid of capacitor color codes eons ago.
