[TenTec] Pegasus 550

Hi all,

     I have a Pegasus 550 with the Auto Tuner option that I bought at Dayton 2000. This radio has performed flawlessly all this time until this weekend. Whenever I try to transmit or tune on 80 meters, the power supply trips on overload. I know it's not an antenna problem as I use the same antenna on other rigs. This tripping on 80 meters happens even with no output power applied. I tried a heaver power supply and it just loads the supply down and dims the lights.

     I have uninstalled & reinstalled the software from the computer as well as re-flash the firmware in the radio. I also looked inside and saw no obvious flashing or burning on the board or components.
 
     I did however notice that the small Hasco relays (14 of them) on the main board seem to have some sort of corrosion on their plastic cover. I have not a clue where that came from. Some of them seemed to have a slight oil film on them. Are these perhaps filled with some sort of dialetric fluid to limit internal arcing and they are leaching it out?

     Anyway, if anyone has any comments or suggestions I would really appreciate them. I would hate to ship it off to Ten-Tec just to discover this is a simple problem that happens all the time with a simple fix.

Thanks
