[Kenwood] Revive a Kenwood TS-520

[Michael Morgan]

I have Kenwood 520 that has been in storage for about 10 years.  It
worked great before being put on a shelf in the corner.  I decided to
dig it out and see how well it worked and when I plugged it in I didn't
get any receive or transmit out.  I get white noise out of the speaker
but nothing else.  Can someone give me any pointers as to what I can
check to try and get this rig working again?
