Hi

Michael Rothacher mentions in L'Amp CCS Addendum that

"So, I tried (D). It uses a self-biased IXYS depletion mode MOSFET
IXTH6N50D2. "

That beast is not easily available (at least in Finland). Could somebody say, is there anything special in IXTH6N50D2 (irreplaceable), or can it be replaced with some other bug (I understand semiconductors but cannot evaluate them)

The IXTH6N50D in almost impossible to buy. Is there some other bug that does its work

Hi All

I just want add this fact to IXYS and Europe. I found out that they have an importer in Swizerland. When I asked them how to get one pair of IXTH6N50D2.

They said it's ok. Minimum ordes is around €200. When I explained the story (I would like do some testing for myself)m, they organized the thing that I could purchase one pair with normal sneding costs. This was well below €200.

So all kudos (praise!) to this company's representatives in Europe.

best wishes HPU
PS
This is meant to be helpful, if somebody else is in the same situation, when I was.

PPS
For various reasons I have not had oppoturnity to build the thing.
