[Yaesu] Sollving the problem of a defective FP29 Power Supply

[Dr. Gerald N. Johnson]

Standard problem in the FT-736r and when I dug in I found all the small 
electrolytics in the power supply were bad. I replaced them with the 
lowest ESR and highest temperature rated electrolytics I could buy and 
its worked ever since. Electrolytics go bad with age. They go bad faster 
when not used. The ones I replaced were all in the switching supply 
control circuits. The power filters from the AC line rectifier and after 
the switching parts checked out fine.

It exhibited the standard problem of pilot light glow for an instant and then dimming to no output. There is no voltage and the fan is inoperative. Not certain if I want to stay with the Yaesu supply.  Has  anyone  addressed a similar problem with the installation  of a  dual voltage   replacement  using a different manufacturer?   I would appreciate if anyone having a similar experience would share the solutions  with me.  Regards, Ron W2CQM/3
