[sdiy] Tempco question

[Michael Schulze]

Thanks to all who have been answering my questions!

I have found the tempco resistors I need, and I can get 5% ones for free.
These will be used to build a BERGFOTRON quad VCO board.  Will the 5%
tolerance be tight enough for the circuit?

The Bergfotron vco is a modification of the ASM1 VCO.  The tempco resistor
is the bottom resistor in a voltage divider between the output of the CV
summing amp and the input of the expo converter npn pair.  So we are talking
a +/- 50 ohm tolerance between a 56k and a 1k.   Geez, at 50/57000 I guess
that's 0.08% of the voltage divider.  Should be ok, no???
