I use plate to plate feedback in all my builds and I will never go back to not using it.

Both Moglia and Broskie have discussed the merits of this type of feedback.

Feedback can deliver some amazing things: lowering / eliminating noise in the driver stage and lower output impedance.

Lots of people summarily dismiss feedback without ever having heard it done properly.

ggetzoff.. you are 100% correct...​

Hi Victor do you have any other pictures which show the space around the Blue Alps potentiometer. It would be nice to be able to have had room to fit a higher quantity option with out needing to slightly reposition the nearby components.

Best wishes for the New Year
Jamie
