OK, so as a sanity check I contacted Icom just to confirm everything so as to make things as easy as possible by avoiding making unnecessary or incorrect changes. Their response follows my query. They sent me the same files on "DB-25 Pin 8 Input Modulation Connection Change in F5061/F6061 Radios" and "F5021/F5121/5011 Series Radios 25 or 15-Pin Connector Signals (OPC-2078 or OPC-1939)" that I had received before from the forum, but they had one new piece of information that contradicts what everyone has been saying about Coffee Bean N, as it applies specifically to F6011/F6021 radios. They also sent me a partial board layout diagram, which I've attached, for the F6061 radio that shows the location of Coffee Bean N, as well as some of the other connect points. Here's what they had to say about Coffee Bean N:

Hello,
Could I get the Board Layout Diagram for the F6011/F6021. I have a mod from Icom that states that it is the same as the F6121 or the F6061. What I need to do is to identify the location of Coffee Bean N so that I can perform the Pin 8 Input Modulation Connection Change in F5061/F6061 per the 6 Jan. 2010 application note. I have the Technical Update Bulletin from 14 July 2015 that shows the location of Coffee Bean T, but that doesn't apply to my older model. I still need to know where Coffee Bean N is.

Greetings,
The IC-F6011/F6021 does not need the N bead modification done on the radio. Attached is the option cable pin out for it.
I am also sending you the jpeg that shows the N bead location on the main board of F5061/6061...
The complete board layouts are only in the Service manual that are only available to authorized Icom Dealers. You can get one by contacting one of the local Dealers near you.
