Question about KRL C-2AQ tempco resistor

[--M]

    I have been working on an ASM-1 starting with the VCO's. I have them
finished except for one part. Yes the "KRL C-2AQ tempco resistor", I
this is a part that can not seem to find anywhere. The docs say you can
replace these with regular 1k resisters i have plenty of these. Anyone
want care to give an opinion, is it worth the effort to locate the
tempco or not.
