To change the front panel isn’t complicated if you possess a modicum of engineering acumen but, if you are an engineering neophyte, then best to send back to PS Audio.!
Tools required: Two cross-head screwdrivers. 9/64 Allen key / wrench.
With the amplifier fully disconnected and devoid of all connecting cables.
Remove the 4 hex screws from the top of each radius corner.
With fingers placed under the ridge at the rear panel pull-upwards and carefully remove the top cover.
Remove the plug/cable from the front standby switch.
Turn the amplifier upside down. Slacken the cross-head screws securing the front footers and fully remove both front footers.
Remove 5 small cross-head screws from the bottom plate (NB: small screws hidden under front footers hence their removal) securing the front panel to the bottom plate.
Put the amplifier right way up.
Remove 4 hex screws ( two screws per radius corner ) gently pull the front panel away from the amplifier heat-sinks.
You will also have to change the four radius corner pieces.
Both rear radius corners are very easy to swap out.
They are secured to the rear panel with 3 cross-head screws per side - then remove the 2 hex screws per corner piece and the radius corners come away from the amplifier heat-sinks.
The front radius corners are secured to the inside of the front panel with cross-head screws - which are accessible when the front panel is removed from the amplifier .
The blue standby switch is secured by two small cross-head screws.
