     A Dyna Stereo 70 keeps blowing the main fuse
     seconds after powering up.  The tubes are fine,
     and they all light up before the fuse blows.  What
     could be causing this?  Is there troubleshooting
     in the manual? (I've heard of a place in Ohio that
     sells Dyna parts - I don't have a manual, but
     think I can get one from them)  If it is the input
     board, I'm thinking about replacing it with one of
     those solid state boards from Sutherland
     Engineering, or from a few other companies.  Has
     anyone tried these things?
 
 
     KUDOS:  to Apogee, for including a new box, and
     grill fabric without additional charge during a
     bass ribbon replacement
 
          to UPS, for cheap insurance rates (~10 cents
     per $100 coverage?).  The girl at the desk
     chuckled, "We're much cheaper than US Mail because
     we don't break things like they do - they *need*
     their insurance."  In my experience, everything I
     have received with (in spite of?) UPS's handling
     has arrived intact and unpunished.
 
     Poo-Poos: to Roadway Express, and Roadway Package
     System (RPS) for seriously damaging three separate
     electronic and two speaker units during their
     handling, then refusing to pay for *anything* by
     writing it all off to "Inadequate Packing" (the
     shipments were all in factory packing).
 
          to Madrigal, for replacing an amplifier's
     shipping box&foam during a repair then charging me
     $100 for it on top of the $230 repair bill
     (included $150 labor for replacing a cap, a
     resistor, and a plastic washer). After this
     repair, the amplifier still arrived with noise in
     the repaired channel.  This amplifier "blew" a
     channel, while driving a pair of LS3/5a's at low
     to moderate loudness levels (I didn't know 3/5a's
     were such a difficult load   ;)
     The last Levinson amp I had, developed a buzzing
     problem while connected to a pair of SMGa's.  I
     love the way Levinson amps sound and image, but am
     curiously disappointed with their seemingly high
     failure rate. These incidents occurred while
     driving what I consider to be simple electronics
     under undemanding circumstances.  Tube stuff (CJ,
     ARC, Dyna, and AVA) has never been this
     unreliable. Has anyone had or heard of similar
     failure rates with ML or other "high-end" gear?
 
     Thanks,
