hi Ron,
Relooked at your dwg, agree top right MOS shows, N channel enhancement MOSFET.
As does my 'copy/paste' from the datasheet for the FQP50N064L, which is listed in the OP's parts list.
Its just that the drawing posted by the OP, shows a 'variant' in that the arrow is in the other direction.
[or am going crazy, (answers on a postcard only, please)]
Ron, I know that you are not nit picking, I welcome our technical interactive posts, hope to have many more!.
Regards
Eric
Comparing the orginal dwg,with your diagrams, 'suggests' a P type depletion, which it cant be???
