One has to remove all the knobs, including the faders. There are MANY screws through the panel AND all the 1/4 inch jack hardware has to be removed. Remove EVERYTHING else BEFORE removing the small screws... It is a LOT of work, although this mixer is small compared to some! Be careful to NOT scratch the circuit board as Behringer uses very small/narrow circut traces that are easily damaged. Make sure you have the EXACT same socket so it not only lines up with the holes but is the right height from the circuit board, Temporarily mount the socket along with the mating ones before soldering the pins so it is in perfect alignment to fit the hole in the panel.
