Narrative:

While radar technician was at the radar site, both beacon channels failed. This resulted in a loss of secondary radar. This is just another problem with the ASR-9 at clt. It appears that our radar is having problems with power surges. There is a modification available to decrease the risk of power surges. Maybe the modification would help our unit.
