[TenTec] Paragon 585

[Bwana Bob]

My sympathy... I fixed my Paragon PLL 2 or 3 times over the years.  This 
summer I fixed multiple PLL problems for a local ham.  His Paragon had 
been off the air for years. After I fixed it, it ran for a week, then 
the power supply pass transistors blew for some unknown reason. He 
switched to a Astron supply and th Paragon ran fine until he reported 
that it was "shutting down" when he increased the power to more than a 
few watts.  Sigh... That guy's Paragon is cursed.  He is now using a 
Kenwood that someone gave him.

73,

Bob
