    keyword=plan to replace raster driver, I'm coming in .....

    We may try replacing the entire "linear driver box" this time, instead of just the 24V supply,
    which was done 3 times in 2 days, I believe.

    Raster supply #7 is the vertical raster linear driver box deployed inside Hall A since Mar 18
    when it was used to replace #5. Hall A drivers are 5,6,7,8 where 5 & 7 are vertical, 6 & 8
    horizontal -- matched to frequency, not that critical but the matching permits optimal
    resonant performance.

    Unit #5 was repaired and left in the yellow radcon cabinet at the entrance to Hall A. Ok, the
    experiment just checked and this supply has disappeared from that cabinet. Too bad. I'll
    come into the lab the hunt for it .....
