200e

My 259e seems quieter than my 261e at certain settings/FM, but then other
settings it seems about as loud as the 261e.  Both the 261e and 259e seem
quieter than the 258v.  I thought it was just me too, but most the odd
things, I chalk them up to Buchla quirks since most don't seem paralyzing
and have some sort of workaround.
