[TenTec] Pegasus Auto Tuner

[John Graves]

John,

I am far from an expert, but I seem to recall that TT used the LDG 
boards early on in both the Pegasus and the Jupiter.  I have seen a 
reference somewhere to the change over to TT tuners.  Also I don't know 
  where or how they changed/bought/whatever the tuner design.  My memory 
gets flakey but it also seems to me that LDG stopped offering the 
Jupiter  internal tuner about the same time.
