Please excuse my ignorance, but I have seen various references to the AF mod and I am not sure what it is supposed to do. Also, where is it located? I have the second receiver installed and I have a bad feeling that in order to get to it I'll have to tear things apart if I decide to do it. Any info would be appreciated.

It was easy job. Yes, it's really worked! Now line-out are worked better! Here is plots "before" and "after" mod. Line-OUT before replaced R19&R20: http://forum.cqham.ru/download.php?id=33360 And AFTER: http://forum.cqham.ru/download.php?id=33361 And new R19&R20 on board :) : http://forum.cqham.ru/download.php?id=33362 Guys from Clifton-labs are clever! 73!
