Dang,, my favorite of all the export radios went out on me the other evening, had this one for about 3 yrs from yeticom, always my go to radio for talking with the locals, went to key it up and noticed there was no meter movement on the radio,, then the radio shut off. fuse blew. this radio has always had the variable power turned all the way down and would run 8-10 WATTS pep running into another small box. finally got around to pulling the covers off and did some basic checks, the finals were showing a short to ground so I pulled the jumper that is back by the finals then my dead short was gone, I powered it up and it receives fine, so one of the 13n10 mosfets went out,, no reason why, I figured it would last many more years running that low of power out of it.
looks like quite a job to get new mosfets in it, double sided smt board and no room,, it looks like the leads bend up through the bottom of the board and are soldered on both sides,, plus I don't know if they took any other parts out when they shorted out
