[TenTec] TenTec Model 254 Tuner Meltdown

[alan geller]

Hello All,
  I wonder if anyone on the list has had a similiar experience. Some years ago I was playing with a new antenna and a contact on the coil of my 254 burnt up during transmitting. I sent for the part, rebuilt it and used it happily with my ONNI V for many years, this time powering the meter light from an independent power supply as a precaution.
  I recently upgraded to an OMNI VI+ and plugged the 254's dial light power connection into the OMVI VI's aux power and wasted one of the small board's (either the SWR pickup or 
  meter driver/adj). Since I never make the same mistake 3 times, I hope, I believe the culprit
  is some sort of ground short thru the dial lamp and/or support bracket design...is this true or
  a known fault?
  Thanks for your help. I really like the 254 when it works.
