DC Specifications for XSM Series

Are there any DC specs for these transformers? What I'm looking for is the max. DC current that can flow through the primary winding without causing the transformer to saturate. If the transformer cannot take a significant DC current, what is the max. unbalanced DC current the transformer can tolerate in a push-pull configuration?


--------------------

The XSM's are not gapped for DC current. About the max they could take is around 10mA. There is some talk around the engineering and sales department about adding a series that is gapped. So, keep an eye out.

Sorry to dig up an old topic, but this advice is for SE. What about PP, where the DC cancels? Example, for a 6N30P preamplifier running about 25mA per side?

Cheers!

As the XSM are design for AC signals, we really do not keep any specifications for DC.
