Galaxy 98VHP Blown mosfet's.

[King Mudduck]

Not my radio.

A friend just had to replace all the mosfet's in the radio but not really sure why. It works fine now so i'm wondering if one mosfet goes out in these radios will it cause the others to blow as well?

blown mosfets

my repairman tells me that high swr will do the mosfet in for sure.Also make sure high dead key isn't more than 60watts .because galaxy gives a warning that it could damage radio I know for fact there alot more heat build up wiyh more than 60 watts.
