[sdiy] tempcos..

Not offhand, but easy enough to find for you.  :-)

They call them Panasonic Metal Film Thermosensitive Chip Resistors.
Page 865 in current catalog (T041)
Part # is:    P + Value + "CDCT-ND",   if you use the 3300ppm/.1W variety.
Price is 10/$5.52.

Values only go up to 1.8k, so you can either modify your circuit to use 
1.8k instead of 2k, or you can use 2 x1k in series, or you can use a 
circuit designed for 1k.  My dial-a-tempco circuit can be set up for any 
convenient tempco value.
