Default FS: two pairs of Bogen MO-200 output transformers

Hi Guys,

I've recently stumbled across something simpler that caught my eye, so I am going to abort this project.

I need to keep the power transformers for the new project, so I only have the output iron for sale now.

These had very good specs:

Bogen MO-200 Specifications

Everyone swears they are 2.1K, but I've tried testing at 20-15khz and I get roughly 5K at all freq.

Asking $175/pr including shipping. They are not light so take this into consideration.

Thanks,

Blair

These have been opened up, wire wheeled and refinished with textured paint as well as have new hardware installed. Will add images today.


Thanks

Can you tell me if these transformers are identical? I see in one of your other posts you were concerned that there may be some difference between the two.

Hi, the transformers came from the same two amps. I still believe it has something to do with the laminate orientation. Each transformer had a quad of 8417 tubes, so I cannot SE as to why one would be different from an electrical perspective considering he wanted the two outputs to sum into a load. Different electrical properties would cause issues if you tried to sum them.
