A coworker of mine has a Cobra 29LX with the IRF520 MOSFET modification. Well, it seems to have stopped working and I was wondering if I could use the IRF523 mosfet in its place (and retune of course). The biggest difference I see is that the breakdown voltage is lower (80v vs 100v) and the drain current is slightly lower. I woudl suspect that the drain current will lower the overall output of the radio, but honestly, i dont really care about that. just want to get him running again. What effects will the 523 have over the 520 thats in there already?
