I had a similar dilemma. I didn't want to spend my time and money on long
distance phone calls/web surfing to find a source of costly tempco resistors.
Maybe you should go another route, it requires little more soldering, but is
definately cheeper than 3$.
I mean you could try my "temperature compensation amplifier". Its tempco is
You could set it on a little perforated board, and replace the
resistor/tempco divider with it.
(For fitting into existing VCOs one could tweak the circuit a little, I
would assist on that if nothing helps!)

I think its worth a try, you could use a tempco later in case you are not

There are no dumb questions, just dumb answers. Hope this one isn't...
