Thanks for answer,

In fact, when I connect trasformer ( only primary, secondery not loaded) the external protect fuse is breaking. I think is a short circuit in the primary or secondery.
I dont know the secondery voltage to repalce with a new one ( probably between 2x25V and 2x35V) ?
If you have an information .

thanks a lot

I do not have the manual or familiar with the specific model but I can tell you that in the past many of the Denon transformers failed due to open thermal circuit breakers that is built in the transformer.
I used to be able to repair a good 95 percent of them by simply adding an external circuit breaker, PROVIDED the transformer winding is not damaged.
Whether it is still the same or that's what you have, I can not be sure?
Classic failures were open primary winding mainly due to overstress.
Happened with both standard and Toroid transformers used extensively throughout their line.

Hello,

I search the shematic or manual service for Denon PMA 100M.
The transformer is out, I want to replace with a new but I dont know the secondery voltage transformer.

thanks, an sorry for my poor english.
