So I was reevaluating my two-channel system and while things were moved about I decided to remove some of the accumulated dust. I was using one of those swiffers on the ES-1 and I guess it is too forceful an instrument as the green glass covering the readout from the digital volume fell into the chassis. So I am going to open it up and remove the glass and re-affix it to the chassis. I realize I need to turn it over and separate the bottom from the top. There appears to be only 4 screws (2 front and 2 back), of the approximately 1 billion screws in the chassis, that actually hold the top and bottom together. This seems way to easy, am I missing something here?
The piece I am trying to retrieve is the glass covering the readout in the image below and the two front screws I believe connect the top to the bottom are the lower screws on each side:
