Wondering if anyone has any suggestions on anyone who can repair some rs-501/502 belt packs? We're located in Central Texas, but so far everyone I've been in contact with doesn't provide repair work to these older units. We're a continually busy event space with neither the expertise or time to learn how to repair these older devices. We have 16 of them that are out of commission right now. We've bought quite a few of the new 701/702s as replacements, but if we could get these working for even half the cost of the new models, it could go a long way to helping our busy times. Just this past semester we had three venues in use by travelling/touring groups who each needed comm provided, but located at areas different then our built-in house areas, but working in conjunction with our in-house crews. Let's just say we pulled some rabbits our of hats and made some magic happen.
