Short of designing one, building it, writing a step-by-step article, and posting a schematic, I'm not sure what more we can do.
Thank you Michael. For the info...
I already read all the info to me available, so I just wanted to know if you guys also thought about it. I see you did...

You probably know that in other operation points the device will akt differently,
so it is not only a mather of switching output caps to make your wine taste more sweet
or more dry.

yes i have tried few ones, but at the end return to michael original value.
but nothing spectacular here , more change in "wine taste" with RES or inductor loading choice and second with input and output caps ..

I also like inductor loading, so I would definitly go
in this direction but try to keep an open mind for other possibilities.
Have you tried some different inductor then hammond?

By the way I have already talked to EDIS who is from Poland I think,
he can make a 300mH 3A plate choke...So this will be another option...)
Hammond is good stuff but I never used it as plate choke.

EDIS told me that:
-core material will be EI96/59
-weight 3.2kg aprox.
-price 44 EUR /pcs
-Lead time 2-3 weeks.

So looks not bad..)

I wanted to order it but then I realized that I dont know in
which direction I should go, high current or high voltage, so I need to decide...)
