24V crowbar


 

I use my FT-980 mainly as a receiver. I have INRAD Xtal 455kHz filters.

So I decided long ago to remove the 24V fuse. I heard alarms about PA destroyed by 24PS failure destroying PA transistors by overvoltage.

But I have never seen a real failure. So I dont know how needed is to install a 24 crowbar. It is simple and easy to connect it at the 24V fuse output. But I have never heard in "serious" forum about the need for the crowbar, o even about overvoltage problems.

Has anybody any notice about it? Or installed a crowbar?
