Equipment repair

Equipping a shop with test equipment to design, tune, and repair radio equipment has turned into an effort to repair test equipment. First, it took 3 SWR indicators (ala HP415E's) and recapping one to finally have one that worked. Then my .01-2.4GHz sweeper threw errors that indicated air flow fault (dead fan) in addition to the 1Khz AM modulation I need to run with the 415 not working. Then the HP 141T spectrum analyzer failed. Arrgggh!
