Canadian RCA CTC-39X Chassis Removal

[hyperlag]

Hello again everyone!

That last thread really helped me out a lot. I've got the power section all sorted and the odd instant on variant control figured out. Since then I've identified some caps that are probably toast and I need to replace my breaker, so I am gearing up to pull the chassis.

For the most part it seems easy to remove with most of the wires on connectors. The speaker looks to be a pain with spades on the fragile terminals, but whatever. The main issue I am having is that the bundle of wires going to the speaker panel/door with the front-picture controls are not on a socket/plug and the door they are connected to has no obvious release.

Does anyone have any tips on how to release this door without damaging anything?
