At least we agree on something.

Nope.

If you ever get a hankering to open up the power supply on that PC
you're abusing I suggest you suppress the urge because you'd have a
conniption fit seeing more parts on just the primary side.

Congratulations on achieving the most ridiculous analogy of the month
in trying to compare a couple of transistors and a half dozen 2
terminal parts 1 amp regulator to a nuclear warhead.

I already have the correct parts and you trying to imply power
N-MOSFETs are 'rare' is just as ridiculous as your nuclear warhead
farce.

Try Mouser. They have over a thousand of just that one type in stock
for 34 cents.

Or maybe you think 1/4W resistors are 'rare'.

No, you're the ****head who can't even remember who he calls ****head.
