Variable NFB mod?

[Roe]

it should go to OT secondary

I ripped out everything I did last night so I can start fresh. Ill give it another go when I get home today but I yeah ,assuming the left and center lugs are jumped together there, I believe the only thing I did differently from the drawing was go to my 4ohm secondary instead of the speaker so it must be something stupid..... I make simple things so complicated sometimes. Thanks for being so patient helpful with us rookies fellas.

I cant see gif on iphone. :/

The wire from the presence or from the other side of the NFB resistor goes to the center lug of the pot. The RIGHT lug then continues on to the NFB resistor or the R selector of choice. The left lug of the added pot remains unused.

Is the control to be placed in the back? Just unwire the NFB wire from the R tap and place it at the center lug, then right lug solders to the selector. Seeemple as that.

took 10 mins to reload and edit. My eyes are way too big for this.
