I found following formula of Hypo Eliminator in
spanish edition of Jacobson / Mannheim "Enlarging" book :
Water - 500cc
Hydrogen Peroxide 3% solution - 125cc
Ammonia 3% solution - 100cc
Water to make 1000cc

Just wander if sombody tried it and if it has any benefits compared
to plain sodium sulfite.

Yes, that's a "Hypo Eliminater" similar to Kodak HE-1. It chemically
reacts the hypo out of the paper instead of just making the washing
process go faster. The peroxide itself will bleach the image so it is
important that it all be washed out of the paper -- but it is very
soluble so washes out quickly.

There are a number of reasons these aren't used any longer, from the
possibility of image bleaching if the paper's left in the tray too
long to the discovery that very small amounts of fixer left in the
paper actually enhance image stability -- this formula will leave
none at all.
