Instructions to Replace Meter Lamps on Technics SE-A5 Amp?

I just got a set of LED lamps for my SE-A5 as my Incandescent originals are starting to go... Does anyone have a set of instructions or a link to a video on how to change these out yourself? I have been looking high and low but nothing so far. I have looked through the Service manual and all it shows is how to take the various sections apart. Nothing specific about the lamps and changing them.You would think knowing how often the original lamps fail that this would be easy to find! Thanks for your help.
