I be oscillatin'

1999-05-04 by Dave Bradley

Just a quick note to tell everyone I've got 2 MOTM-300 VCOs up and running.
It would have been perfect except that I reversed a couple of resistors and
was greeted with silence when I fired them up first.

Excellent kit, Paul, congrats!

The only thing I would warn other builders about is the precision
resistors. A few are metal cans with the value printed on, but many have
blue bodies, and the color code is totally worthless. I ended up measuring
each one to figure out its value. A little extra care here can prevent
hassles later.

Well, I'm back to test some more and calibrate!

I always use my DMM to check resistor values when I assemble.  I find it easier.
