Hello,
I've got a schematic wich said to use a 20H choke. Is it the correct value for this amp ?

My 45/100 has the 352-114 choke. I have remade those:

I have seen a few amps with actual 20H chokes. I would say to contact Brian Wallace for one of those:

On my first 45/100 clone I straddled the line between what the schematic said and what the amps usually had -- I chose a 10H Heyboer.
My '65 Super PA repro uses the Marstran 20H RS clone.

Both sound great, the somewhat underrated RS choke may ghost a touch more but not by very much, both amps sound pretty comparable and have a great organic feel to them.........
