Tempco's

[chrisc at metrics.co.uk]

Hi
     If what has been said on the list i scorrect re: the tempco in Gene's 
VCO circuit needing to go *UP* in resistance with increasing temperature 
then those of us in UK definitely *CAN'T* use Farnell PN 143-584.
     I'm investigating the possibilities either of getting a correct 
positive tempco for the 1K part or else replacing the 56K with a negative 
tempco. If we use the 10K equivalent to 143-584, we'd need a normal 180R 
resistor where the 1K was. Will a load of 10180R be too low for the circuit 
that was designed with a load of 57000R in mind?
Answers please..... I've got one of the British tempco catalogues, and I'm 
awaiting another.
We live in hope.....
