do these guys not know what gate drive ICs are or something? it's not as shitty as the TS100, but it's still somewhat awful. also not too sure why they're using two FETs in anti-series, is backwards current flow a potential issue somehow?

if they used a proper gate drive circuit and an overkill FET it might be able to run at like 48VDC, with a sufficiently conservative PID. or be powerful enough to run a T245 tip if you swap out the mounting hardware.
