I use 3 Kodak Carousel S-AV 2050 AF and one Kodak Carousel S-AV 2050, 4 PAX-SAV ADAPTOR 3430, have no Dataton 24 VAC supply, the first SAV-Adaptor is connected to a S-AV 2050 AF ... and this configuration worked for years. But suddenly my PAX didn't work at all - so I started to look for a "new" one ....
