The Dual 505-1 record player in Pleiades


Serial number: 170058


It had been found abandoned on the pavement.


No dust cover.


Turntable rotated but there was smoke and a bad odor after some seconds.


Motor bearing had been lubricated. Smoke had stopped.


Belt was very slack.


The one that arrived by post never quite worked properly while changing from (33+1/3)rpm to 45rpm.


Then one rubber belt of less width had been bought from a local electronic spares shop which did the job even worse. Many hours were spent with different diameters. Angular velocity would not change. It was abandoned.


After a few years it was dusted off again for a listen. It worked almost immediatly by removing the belt and replacing it with itself. Angular velocity now changes! Time heals.


It has an Ortofon moving magnet cartridge type TKS 49S. The stylus says DN149S. See next post.


Listening tests were done on various minimum electron components systems, see this week's posts.


Frequency response and smoothness is so extended on both extremes of perceived by brain spectrum, it is amazing.


Sends digital to the cleaners.
