[Amps] Advanced Radio Devices Model 230C

[Mike & Becca Krzystyniak]

     I picked up an ARD-230C Linear Amp from a friend exiting the hobby.
The amp uses three 3CX800's and appears to be 160m - 10m auto tune with a
remote head.   But I do not have any other docs with it.  He had it in
storage for the past 10 years or so.  It powers up but there is no display
to the remote consolde.  I looked it over and do not see anything obvious.
And of course I have no manual.

   Anyone out there with one of these?  Is there a manual?  Was there a
trouble tree or in case of difficulty section?  

   This is a cute little floor mount remote amp.  Or should I cut my losses
and plan on scrapping it out? 

Thanks in advance for your help and comments.
