   I'm on the lookout for a good generic spring reverb driver circuit, now
   that I have an 18" Accutronics box.

   I found one in an old book of electronic circuits.  It basically has a two
   watt amp IC (LM 377) pumping audio into the reverb, then two stages of low
   noise preamping (LM387) at the other end.  I think this is a good way to
   go, but would be interested in what any of you gurus and veterans might
   have to offer.

You'd like to know what folks think of using this circuit with this
reverb tank but you won't tell us the model number of the tank or the
source of the circuit?  Hmmmm.

Accutronics makes numerous models of tanks in various sizes, types,
decay parameters, input impedances and output impedances.  It's
clearly a good idea to get a circuit matched to the tank.  Accutronics
will gladly send you a book of circuits, hints, and recommendations
for free, just ask them.

   I have heard (can't remember where) that the Accutronics spring units 
   come in different models, with different transducer impedances. Is 
   this true, anybody? Also I seem to remember that some tanks had a 
   sticker on them with a humorous comment about the place of 
   manufacture.

No, that's another company.  The label said something like "Made with
pride by beautiful girls in Green Bay Wisconsin".  I can't remember
the company's name right now -- anybody know?  Are they still in
business?
