Tempcos

[Steven Cook]

Hi,

I'm not sure if this is any use, but I have a Powertran Transcendent 2000
synth which uses a network of 2 resistors in series in place of a Q81 in
the VCO. I quote from the construction notes:

...it just so happens that copper has a TC of +3900ppm/C. Therefore a 870R
copper wirewound resistor in series with a 130R metal oxide resistor looks
like a 1k resistor with a +3400ppm/C TC.

This is not exactly the same as the +3500ppm/C resistor mentioned in these
posts but may be of use.
