Full Track Productions is owned by Dave Dintenfass and located in Seattle. Dave specializes in the restoration and repair of Ampex 300 and 350 series machines - only mono and stereo versions. Dave built the Herniator, a custom 30 ips capable 351 with Shafer tube playback electronics, that we used in the Bottlehead room at VSAC 2003. Dave is known in particular for supplying replacement cork turntable pads and pinch wheels as well as refurbed capstan/flywheel assemblies for these classic studio workhorses.
