[Kenwood] TS-50 problem

[cemilton at aol.com]

I have a TS-50 that I recently brought back on line and found that everything worked...….except the output power into a 50ohm dummy load was a whopping 200 watts.  I immediately stopped, went to SSB mode and whistled up 200watts.  A quick try in CW and AM produced the same results.
 
I had this rig repaired a few years back by Clif @ AVVID.  He put it in tip-top shape and I used it periodically afterward.  Fast forward to now (3+ years later) when I got it from the closet and found the above described problem.  It's been in a controlled environment and not subjected to humidity or high temperatures.

I'm guessing an electrolytic has given up and the bias on the finals is in trouble.  But that's only a guess.  Anyone wish to comment?  I'm not equipped to service it unless there is something obvious that doesn't require precision work.  I'm one of the dinosaurs who is linked to BA gear where I still do my own repairs, etc.

Thanks for the read.
