Hello. I searched around a good bit before posting I hope this is in the right place. Anyways I have a 99v with blown finals. The driver is still good it has the 2312s for the dual finals. The 2166 driver is still good. I could simply order some hg finals but I have some NEW IRF520S on hand and I would like to just swap it over. I can't find much info on what to do to make it mosfet friendly. Any help is appreciated.
