Thanks for the prompt reply. The panel I want to remove is the control panel with all the buttons below the glass display panel that shows the direction of the tape, levels and so forth.
I don’t think the control panel with the buttons, 0-9, memo, stand by etc, is made of aluminum. Maybe it is but if it is its black.
Is your response intended for the panel I am describing? I have attached a photo of the circuit board I need to get to that is covered by the control panel. The photo is of a Beocord 9000 but the area of the unit is what I am trying to convey.
