for my mots (Rpri=2r, Rsec=115r ) 2k it`s about 5.4H, that means the
coupling is 0.98 - the same as i  measured, ok then :-)
and 600r means that coupling has increased to 0.997 - ha, THAT is a
"real" tranny, even too much  (for such geometry i guess), so probably
our mots are not so equal :-D

> As a result I run with the shunts removed on mine.

the question is - what benefit would we have from this (if any)?
coz in my case i need about 40H when the coupling is 0.999 - i`m just
too lazy for this :-)

it`s not a problem to get 81" - the problem is how long your tc
would be working, before the mot`ll  melt down ;-) i`m building
_continuous_ duty psu.
