[Hammarlund] SP-600 AVC line levels at spec'd inputs.

Hi Gang!!

    Making my way through an SP-600/JX-28.  It's been PHUN!!  I've 
gotten it working, but was looking for a piece of info not found in the 
service manuals that I've been looking at.  Does anyone know (or can 
you/they measure) the AVC line levels (voltage is what we're looking 
for) that should be found when the receiver is running at spec.  The 
manuals call for 2 to 3 uV in at the antenna and should produce .667 mW 
across a 600 ohm load (20 volts I believe is what the manual calls out). 
I'm asking because I'm chasing several issues in this receiver and I had 
to wind replacements for the AM detector and AVC line coupling 
transformers.
If you don't have a JX-28 you won't know what the transformers are, but 
you may have the rest of the info.  I'd like to be able to verify the 
AVC line levels to be sure that I have enough drive for the AVC line.  I 
can rewind the transformers if I need to.

TIA!!!
