Put the feet back on their screws. Not going to be easy now but you should try and get the feet started on the thread, then pull on it to keep the screw from rotating and finger tighten the feet as much as you can.
Remove any other screws in the bottom of the cabinet. Six as I recall???
Push the front panel towards the ?rear and remove the tuner box as one unit though this is typically quite tight. If someone has not used the original screws on the inner cover this can be REALLY tough! You will hear some scraping.
If the top, bottom, or sides have been compressed inwards, this will also complicate removal of the inner box. Try to straighten it as best you can.
