Hey Phil, i will give it a shot The model WVBM500 is one piece of WVBM503 which is 3 monitors mounted into a specialy designed rack system. I doubt if you could find a replacement to fit back into the rack as these are older units. The jacks on the back are for (looking from the back left to right) video in, video out, sync in, sync out. I do have service literature on microfiche if needed. Tritronics also sells security systems and replacement pieces from speco "pro video" which are in our online cataloge. Hope these tidbits are helpfull & give a ring if i can be of any other assistance. ************************************************* Kevin Harris kharris@xxxxxxxxxxxxxxxxx 800-638-3328 x1241 Tritronics Inc.

These have four BNC connectors on rear, black and white 5" screens for security use. I need to know a good source for these at a reasonable cost in case these are shot. I was asked if I could get them. So, anyone know a good parts source, or wholesale sale source? Phil Bader -- Philip Bader Jan Phyl TV Inc. (estab. 1976) 3420 Recker Hwy.
