07/04/26 : 1427 Mhz downed the South Linac when it died and opened breaker in 02-SL-PP. Amplifier was replaced by C.Kerns, C.Hovator, T. Plawski and attenuated for a close approx. power. South Linac was ut back into RF and Thomasz and I put some panels up to shield RF and eliminate GLDER errors in the South.

After resetting the power breaker, powered on the amflifier and had no power out or power on led. Replaced the amplifier with a ready spare and trimmed the ouput for correct output. Had to put up a couple of door blocks around the cabinet to minimize RF leakage causing GLDE warnings. Machine back to OPS with normal RF. S/N of removed amp was 001/8174. Installed amp was S/N 002 8969. Kurt H., David G. , Thomasz P., Chris Kerns. Happy 4th and beam on !!
