[TenTec] ORION died

[Pfizenmayer]

Think you are probably right Carl - at least hopefully -(it has gotten even 
worse now so looks very much like a regulator going kaput ) - but I just 
looked at the 81917A7 CPU/DSP regulator schematic  and they are things I 
cannot get locally tomorrow and get them installed by 2pm so I guess I will 
set the O aside and hook up my TR7/R7.But maybe I can avoid a trip back to 
TT with it. Besides I am not looking forward to pulling the front panel 
again to get to those regulators!
