I have fixed a similar problem previously - replaced the si5351, driver chip and finals - I just don't see the point if it's going to blow up again.? I haven't had this problem with other QRPLabs products - I'm just finding the QDX to be less robust to my sometimes less than ideal operating practices. To be clear, I fully understand that I exposed the unit to conditions that caused it to blow up.
I suppose I could use it as a dedicated receive only monitor which would eliminate the possibility of a poor mismatch on tx taking everything out again.
