I don't know of any solo pools....but I do know there's a "obsolete" project on github called "stratum solo mining".....and that should fix antminers penchant for adding "stratum+tcp://" to any URL chosen to point a miner at.
I know about this as, I'm a miner at heart.....and my S5's my C1 and my S3+'s add that accursed stratum+tcp:// to any URL that's pointing at a wallet for solomining.

Why antminer decide to do this is beyond me.....unless that is, they think that miners are too stupid to set up their own gear.

(edited in) my S1's don't add that accursed stratum+tcp://......so one might want to reactivate their S1's and point them at a local wallet......or a pool if they so choose
