Oh yes I tested them before they went in, lol, I know you are not to blame here. I think something is up with the amp. 


oh lord there is no way it got that hot


As I understand it running it at '6' is like the switch is not even there.


I have an old Palomar TX-150, 2 x MRF455, I run it on the same radio all day long, sounds great, no complaints.

So if that radio is not overdriving a 2 x MRF455, then there is not way it will overdrive a 4 x MRF453, we are only talking about 15 PEP on SSB, I was planning to remove that switch and make room for something else


unless tuning it up to '6' is somehow multiplying the power coming out of the radio before it hits the pills then I can't see how it would effect the pills, it's not like we are hitting it with 50 watts in
