(Also a query about the resistor value: does it truly have to be 13K?
Is this potential divider so critical that it cannot use one of the
readily available standard values of 15K, 12K or even 10K?)

When the mod was first published I asked:
"Just checking to see if this is a typo.  13K or 12K?"

Bob Friess N6CM (the 1st mixer designer) replied:
"13K is a standard 5% value and is correct."

I took the 5% tolerance to mean the value is somewhat critical.
