A few years ago I wrote a document about an easier way to do this adjustment than what's documented in the tech refs. Well, I just found an even easier way to do it and updated my document with it. All that is required is a VTVM. Here's a link to it on our website: R390A-BFO-Neut-Improved.pdf <https://www.r-390a.net/R390A-BFO-Neut-Improved.pdf>. This procedure should work on all 390s.
