Tried, but could not reach Fay, Mark, Riad in advance, but finally we removed the GTS unit, jumpers are documented and are on the desk.  That unit is now in CEBAF, worked fine over the weekend.

Fay wrote me they're using a function generator instead now, so didn't sound urgent to return sooner.   If I have this wrong, let me know....
