Thanks for the input @nigelwright7557. I will check the drivers as well if I find an output blown and will watch out reversed parts!
Yes , I do that with my designs , run the FB right from the drivers. You can run the outputs independently , as well. 10K from V+/- to +/- drive at the outputsSplit R532a in 2x 120ohm in series and use the midpoint as connection for the negative feedback. Than I expect no issues, even at full rail voltages.
(5-6mA VAS current).
