Also, keep in mind that if you plan to move from the IRF510 to the RD16HHF1,?
the uBitx final should have some adjustments to the transformer ratios and such.
The RD16HHF1 is not quite a drop in replacement.

Allison has quite a few posts here.
None have discouraged experimentation with the IRF510's.
Quite the contrary.

She did however suggest you get your RF parts from reliable vendors,
be they IRF510's or RD16HHF1's.

Gents and ladies, I don't post much as I'm a busy broadcast engineer.? But I try to read often.
Allison's post contains wisdom.

Education tends to be expensive.? If your goal is IRF R&D, then knock yourselves out.? You will go through a lot of parts, and likely as not, spend a lot more time and money in acquiring the knowledge and experience.? In the end, you'll know what a part can or cannot do.? If that's YOUR goal, great.

For myself, my time is worth something to me.? I think it's false economy of both my time and money to blow up a few dozen $0.50 parts, chasing issues created by the selection of an inferior part from an unreliable source, when one appropriately selected and sourced $4.75 part will accomplish MY goal - to use a piece of equipment that I built.? The former is not worth the hassle.

If you need a cliche, here's two:? I'd like to "not reinvent the wheel," but would much rather "stand on the shoulders of giants."

Two cents duly submitted.
