What are those ringing sounds that computer processors make?
I can't keep a tube here because I will hear it _going_ all
the time. And more than I few folks are insufferable to
listen to on the talk radio-- things I never used to listen
to but now that streaming audio is available I have been able to find
more quality discussion

OTOH I can listen to a table radio and be, you know, _happy_
if something good is playing.
