Over 50 years ago, Mike Dorrough introduced the Discriminate Audio Processor - the DAP 310. Broadcasters that cared about audio quality started buying and installing DAP310s to improve the audio quality of their stations. Five decades later these old audio processors are still in demand - as are services to supply parts and repairs. Randy Swaffer and Mike Phillips are two DAP310 enthusiasts - and they know all about repairing and aligning these classic units. Jordan Tuck also joins us to talk about refurbishing other broadcast gear, including a Continental Electronics FM transmitter and an A-6000 audio console.
