Re: RD16HHF1 power curve flattening...some

Did you reroute the pins on the RD16HHF!, the are in a different arrangement than the IRF510.  The IRF510 is GDS, the RD16HHF1 is GSD.  Swapping the source and drain will blow the fuse like that.

Hi everyone,

I tried to do this mod: https://ubitx.net/2018/02/16/power-amp-fix/

I checked everything for shorts, and a multimeter connected to the power input shows typical capacitor behaviour. However, when I connect power, my 3A fuse instantly pops. Is it possible that fake RD16HHF1 are causing this? I'm kinda desperate.
