Hi Andrew,
Yes, place that 2.7KΩ resistor across RP2 pins 7 & 8. This resistor is
on the output of U6A to drive the varactor diodes in the PLL Osciillator
circuit. It was changed to 2.7K in Rev B. In Rev A it was 100K and part
of RP2, so you are just placing a 2.7k resistor in parallel with th
Hi Dave -
My s/n 892 currently has RP2 = 10k, not 100k. Does the 2.7k still need to
be added across pins 7 and 8?
From the PLL Ref Upgrade kit docs (E850138), it sounds like it might need
to be added regardless of 10k/100k, as the first step below doesn't
differentiate, while the next step does:
Correct Andrew. Even if it is a 10K RP you'll still want to add R19.
I just got done fully upgrading a field test K2 here and had 100K stuck
in my head. But it is the same whether 100K or 10K RP's.
