QRS model 15 wind-up phonograph

[truetone36]

QRS was a manufacturer of player pianos and piano rolls. This machine dates from the mid-1920's. These were entry-level machines which sold for around $15 new. Is your noise a rumble coming from the motor? If so, it's most likely dried up grease gumming up the works. This is a common issue in unrestored spring-wound phonographs. If the noise is a rattle heard while playing a record, then the gaskets on your soundbox need to be replaced. This is also a common issue. Two to three records per full winding is about all these machines will do due to the small single-spring motors they have.
