[Heathkit] HW-9 Actual vs Schematic

I would be VERY interested in knowing if these are known differences (I can't 
find them) AND if there are others that I've missed so far.
 
In the "REL PWR/OUT" circuit: 
C569 (the filter cap) is shown as .01 on the schematic. But in the assembly 
manual it is listed as .1uF. Anyone know which is correct? Or does it even make 
a difference?
 
In the Meter circuit:
The schematic shows the regulated 9 Volt connected to one side of R332, the 
other side of R332 goes to R322 (to the Drain of Q302) and to R333 (the Meter 
Zero Pot).
At least on my T/R board, one side of R332 is connected to R333 (as in the 
schematic). However the other side of R332 is connected to R322 (which is 
connected to the Drain) with the 9 Volts being fed at the junction of R332 & R322.
If this isn't clear, I can provide a simple drawing...
 
My schematic is Copyright 1984 and is listed as "Part of 595-3059".
 
Thanks, Don - K4BEV
