(40) A regulation in The Netherlands is for similar aging cabinets in each neon shop. This cabinet was built by Dirk Boonstra as well. The cabinet is totally self-contained with four aging transformers, individual mA controllers and on/off switches. All power to the transformers is disconnected once the sliding door is opened (each side of the cabinet has a door that slides toward the center). The units are hung on the screen with clips and the high voltage leads are then connected. [ View Picture ]
