Gentlemen I'm not sure if this is the right forum but maybe someone has some 
ideas.

I have a Icom IC-775DSP.  Over the Sweep Stakes weekend it blew up an hour into 
the contest.  The cause of the failure was the same as the failure I had last 
summer; one of the output power transistors blew when I change bands and hit 
the tune button.  

It appears when going from one band to another then hitting the tune button the 
tuner is in a state causing excessive current to flow to the power FET's 
causing failure.  

I've heard of tuning for maximum smoke but two failures like this getting 
expensive.

If anyone knows of a mod to prevent this from happening again I'd appreciate 
it.  


73,

John
