To all MOT users,

It's time to reach a consensus regarding whether to leave in or remove the
shunts.  From the below, it seems Tim J would vote to remove them.  Assuming
one controls the primary current by some means other than the MOT magnetic
shunts (e.g. ballast, DC resonant chargers or H-bridges, etc.), then what
are the performance pros & cons of shunt removal?

Thanks,
--Steve Young
