Are you sure it is the correct rectifier, i.e. an 83 mercury-vapor rectifier, and not something like an 83-v which is not mercury-vapor? You said that the tubes are new, but are they old American-made stock or are they recent imports which may not be the actual tubes that they are marked as? Are both of the panel lamps old-stock type 55, and not some newer "55" from China? Did you check all of the internal settings shown in the "Service Information" section of the manual?
