Does anyone know what happened to SUMO Electronics?

Just received a response from Jason Stoddard.  He said he never heard of the Sumo Electra, and would only talk about Schiit. So with this said and Jim gone, I looked on YouTube, and there are two videos about Sumo. A Diana pre and Ten poweramp, and  a Sumo, Nine Plus amp. No help at all.
I think I found a schematic, but  am not sure if it's the correct one. The model number matches, but  It doesn't look complete.

Going to continue the hunt.

JD, am I understanding that you are after an Electra Schematic? I'm not sure, but I may have one.  Please confirm before I go crazy looking. 

Here you go,  this should help.

Thank you timlub!

This will go a long way to helping me repair the pre amp.
I was correct, I only had half of it.

Thanks again for filling in the the other half!

The Charlie tuner I had was made by Sumo.
