To stop any smaller radio from falling over,
you can purchase a book holder from an office supply store or
a collector dish holder (from a Hallmark card shop) . With a little
adjustment you'll have a
"tip resistant" radio for a lot less then it would cost to fix or
replace the radio. I've seen plate holders for about 2 bucks that are
made of coated very heavy wire that you can bend to adjust to a good
viewing angle. Hope this helps.
