You might be able to just substitute the 20K with a 25K and it would work
fine. Depending on its function in the circuit, the value of a resistor is
often not critical. I made a similar substitution with the voltage divider
in the bias supply of my Gates BC1-T and could tell absolutely no
difference. In older rigs with carbon resistors, some the resistances may
have shifted a greater percentage than that, but the circuits still work OK.
