There is one way to cheat if all you have is ECs. An EC will
maintain better than 5ppm from +32 degrees F to above 120 degrees F
only if you have a stable +5v DC voltage on the compensation line.
Kevin,
Would it be better to replace the 2 resistors with a small low current
TO-92 +5v regulator.
That will provide a more stable voltage and is smaller than 2 resistors.
Just my 2ยข
