I want to remove the KMA20, Dual HX170B's and KT76 from their trays so that
I can easily clean up all the knobs faceplates etc.
What special tools do I need to remove them ? And ... Where can I purchase ?

To remove the radios, just a 3/32" allen wrench, available in the
aircraft department at Lowe's, Home Depot, Sears, and other choice
tool houses.

Careful when you pull the radios, gently rock them side to side by the
edges, without pulling on the knobs.

If you want to disassemble further, proceed with caution. The front
panel assembly on the KX170's is a pain in the ass to put together
right if you mess up the numbered wheels, and --trust me on this one--
the springs are the same color as your hangar floor.
