Tigers and 'Pines,
We are fortunate that Theodore (Tod) Brown has prepared a fine article
on "How to Install a Radio in Your Sunbeam". This well illustrated
article thoroughly describes methods, sources, and options. There is
even a side piece on removable enclosure/radio capability and a 'sneak'
speaker installation technique.
Worth reading on <http://www.TigersUnited.com> under the "Articles"
heading / the "Articles" underscored hot link.
