You can find a clue by finding the voltage on each side of the original fc. Note the voltage drop across it. Then do a rough calculation of the hv current that passes thru it. Then you can use ohms law to figure the resistance of the original. There would be a pretty big difference between 2k and 7k.
Or check the plate voltage on the 45's against the known voltage on the chart. If it's high like 50 or 60v w/the 2k fc in place it's probably too low in resistance.

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
