[sdiy] russian synths

[Czech Martin]

Well, if no load is connected to a transformer,
the only current needed is for the main inductance
(t principle schematic of a trafo).
Or in other words: the very large main inductance will
controll the current.
This current will create some losses in the wire
resistance and magnetisation "resistance".

Since X=w*L, the current will depent linearly on frequency.
The losses I expect to depend by P ~ I**2, the square 
of current.

Perhaps this is far too easy, but should give an idea.
Look how warm the transformer will get. Everything
above 50C is alarming.

m.c.

hello everyone.
i've got a couple of synths from russia: polivoks and ritm-2.
they call for 50 hertz.
i can get step up transformers to deal with the voltage but not frequency.
will i have problems with the wrong frequency?
any thoughts on what to do?

thank you for any input you may offer.
