Kyocera A710 - front knob removal

[saucerman]

Hey everyone, I'm attempting to clean up and "restore" a recently acquired Kyocera A-710. Somehow the big 4 front knobs are all misaligned relative to their correct center notches. I'm trying to remove them to set them in the correct position with no luck. I've tried Allen keys, various screwdrivers, all with no luck. Does anyone know how to remove them?

Part #21 for reference in the photos

It would likely be an allen key. Occasionally a slot screwdriver. You should be able to look inside the hole with the right flashlight and see what you need and make sure it isn't stripped.

Guessing you just haven't tried the right allen key. Or it is stripped.

There is another Allen like key that has 5 corners on it and a hole in the middle, but I don't know what they're called. They are intended to make removal of a screw using that fastener type difficult to do without that particular tool.

There's all sorts of weird security bits. But I've never seen one holding a knob on a vintage receiver.

Maybe that's done to discourage disassembly of the equipment. You know, someone disassembles the equipment, get an electric shock or other injury, and then tries to sue the equipment manufacturer.
