The Collaro Studio was the next generation of record player autochangers from Collaro after the Conquest.
There are several differences and improvements over the Collaro Conquest, the pictorial guide to servicing of which can be found
here
The differences are:
Improved tone arm with adjustable tracking force (on some pick up arms)
Improved speed selector
Motor mounted on rubber mounts to stop vibration
Quieter change cycle mechanism
User adjustable set down position
User adjustable pick up arm height.
The example I'm working on is a Magnavox Imperial. Magnavox bought out Collaro and the brand all but disappeared from the UK.
