Hi Duke,

First I apologize if my question will look rather stupid.
Don't have experience with OTL, alltough I read only good things about it.

I have Magnepan 20.1 speaker, with very low efficency. They  are a rather simple( constant ) 4 Ohm load. Is there any chance or possibility to be driven by OTL. Maybe the lower end would still have to be on SS  or you have any experience on that?
Thanks in advance.

A large OTL like the Atma-Sphere MA-1 works fine on Maggies.   Give Ralph Karsten a call and ask him, as my memory has grown foggy, but my recollection is that Wendell Diller made an amazingly favorable comment to him after hearing MA-1s driving Maggies.

Thanks, I am a bit nervous to change from ss to all tube especially to otl.
Have also found a Graaf gm200 which could work fine, maybe a zero transformer would have to be the last step to make the perfect conditions...
