Hi John,
    I can't solve this problem, but can offer sympathy & a tip.
    I am "memory impaired", and sometimes have trouble remembering the next
day, what I did to a particular ckt.  I've found that I must make notes &
sketches of stuff, particularly in a case like yours, where I remove
something for future replacement (even if the future is a only few hours
later).  I've gotten a digicam, which also finds use in this manner.
    If nobody solves your query quickly, I'll go take a color digipic of
that area in a 390A for you.

I just replaced the original Carrier Level adjustment pot with a 10 turn
pot and was interrupted.  As a result, I forgot where the three wires were
placed.  There is a white wire which comes from the IF gain control, a blue
and orange striped wire and a green and blue striped wire.  I know two
wires attach to the center pin, but I'm not sure which two.
Memory fade is a terrible thing!  Can someone help?
Thanks
John
