Sounds like alot of my days lately. OEM HV splitters that last a month.
SSB boards that the famous diode is supposed to go bad and replacing it
has never repaired one for me yet. Toshiba that blows Q 404 and F470 after
replacing all three anode wires (that is usually the problem). I'm getting
older and cannot concentrate like I use to. also ringing in my left ear
that doc said is due to a small TIA (stroke). I have about had it, and
21/2 years till I'm 62.
