Hafler 9130 power amp


I bought a nos power switch for my Hafler 9130. Can anyone provide me with instructions on how to install it? Thanks!

I've never repaired a 9130, but just looked online and found a few images... The Power switch wiring has plugs on it,  simply unplug the unit,  take the top off,  Hold your new switch next to your old, remove and exchange the wiring from the old switch to the same position on the new switch.  I can't see the mounting,  but it can't be much... A couple of screws,  replace the in reverse order.  I bet you are more capable than you are giving yourself credit.  Go for it,  it'll be done before you know what happened. 
Remove the top plate and you’ll find the switch’s wiring has double-crimp disconnects. Possibly- a capacitor(.01uF), across two of the terminals, to minimize turn-on transients. Before removal, annotate the wiring and switch orientation(ie: LED on the bottom of the rocker). Once you remove the wires, you’ll find expanding retainers on the switch body. Compress those, and the switch should easily push out, through the front plate. Reverse that order, to reassemble.
I want to thank everyone who weighed in to help, especially Rodman99999. Your input is most appreciated!!!

The expanding retainers are on the side of the switch.  Just push relatively hard and the like rodman stated, it pushes out from the faceplate (push from the inside out).  The new just snaps back into the faceplate from the outside in.
