No need inductor, but there is mistakes on your board...

So I have been reading over this post for about 2 hours. I'm looking for boards to build the HV23 but not really finding those. Do they exist or is it possible to get gerbers and place order.
thats quick Andrew, . meanwhile i made another version. but the one you already made is best.
just remember to use metal film / carbon film for the zobel Resistor, as wirewounds can cause oscillation . just something i learnt recently on Mooly's mosfet amp thread.

Hi Jacques,
Here are the pdf and gerbers. These are diy designs kindly provided by APEX, so no issues in posting.

Thanks Prasi.
I just completed the 'doctoring' of your purple image with Photoshop to generate a laser-printable BW image 😀😀😀!
Cheers,
Jacques
Looking good Andrew, Prasi is indeed very good with his layouts.🙂
What rail voltage are you using ?

Hi Andrew,
Congratulations for your build!
Did you change any resistor value from the schematics for running at 30V instead of 55V ?
Cheers,
Jacques
So just asking again are there boards for the HV23 version with 4-5 transistors per side available. Or possibly gerbers?
