Hope someone can lead me in the right direction. I have been using a Galaxy 959 for several months now as a base unit. It was tweaked and peaked and was doing about 30 to 35 watts on SSB and about 20 watts a.m. . Now all of a sudden the radio will only do about 10 or 12 watts SSB and 4 watts a.m. I have several radios inline all are working fine . Match on Imax is 1.1 so it is not an inline problem . The radio still talks fine got great reports on modulation.Still making DX contacts QRP. Just the power has dropped off. Thinking maybe finals are going south . Uses IRF 520 finals . Any help or sugestions would be appreciated. Thanks
Joe

My galaxy has had problems with cold souder, you can take the top cover off and touch the board all over and see if it helps, while talking on it. If this doesn't help, you could have a problem with the final or driver power.

Well all is well again with galaxy. Got some new mosfets in from china. (How can I go wrong $2.00 each free shipping) Swapped out driver and final and got my full power back. I did turn the radio down a little on tuneup. I hope this will help mosfets last a little while longer. I am A happy camper now. Joe
