Re: Blown final club? I think I have a membership


 

I think Jeff has had his FT817 working, just started giving low power indications.

I also think he said he had tested on dummy load and meter.? If not that would be the better test.

I have blown finals after I lent to son.? I put off getting new finals board, and now it looks like I have an expensive brick with very low time on it.? I saw some recently say they ordered the boards, and some say they are unavailable.? What is the real story?? Is there an alternative that tossing the 817 in electronics recycling?

Hi Jeff,

?

You have to remember that there are over a quarter of a million of the units out there so there are bound to be some failures.

?

Remember, also, that the early units with the bipolar transistors were more prone to taking off under low battery conditions and blowing up the finals due to there being no load on them

On first blush, that appears to be an excessively high mortality rate. Any thoughts on "the why" of it all?
