We propose 4 new Chandra observations of NGC4697, the nearest X-ray-faint, optically-bright elliptical, which was resolved into low mass X-ray binaries {LMXBs} in Cycle 1. We will detect LMXBs at least three times fainter { 1e37 ergs/s} than possible for any luminous E galaxy at present, allowing a direct comparison with the LMXBs in our Galaxy and M31. We will measure the variability of sources on times up to 4.5 yr. Models predict variability for LMXBs in early-type galaxies, which is particularly strong for the brightest black hole sources. We also propose 1 orbit of HST to detect >1500 globular clusters {GCs}. If the results for luminous LMXBs continue to low LX, most of the LMXBs will be identified with GCs. We will study the formation history of LMXBs, GCs, and field stars in N4697.
