In Reply to: Sorry, per the 9000ES service manual, posted by Allen Wright on April 9, 2007 at 06:29:01:
Hi Allen,
I'm looking for a Hammond step down. There is one toridal and one Ei type. The toroidal provides isolation, as they stated on the features.
Why I need 100VZ VA power rating? Why this can provide a line filter?
Thanks in advance.
Greetings to your beautiful city!!

Hi,
> I'm looking for a Hammond step down. There is one toridal and one Ei type. The toroidal provides isolation, as they stated on the features <Not in my experience - toroids couple high frequecy hash and noise far more than an EI core transformer - unless they have made the toriodal in very special way.
> Why I need 100VZ VA power rating? <
Becuase it's far more than the player needs, therefore will not limit the player. A smaller transformer may well cause a loss of dynamics or other sonic problem.
> Why this can provide a line filter? <
Because, if it is a EI core, with the primary and secondard windings on separate bobbins, the high frequency response of such a transformer is poor - hence the high frequency noise & hash present on ALL wall supplies will not transfer to the player.

You know Schaffhausen?
Hi Allen,
I spend a few beautifull days on Munich a few years ago, but I do not know Schaffhausen.
Thanks a lot for your answers. I have the oportunity to get a 9000 or a 999, but, its seems that the 9000 is the best choice.
Best regards,
Beto
