Vari-speed adjuster
Semi automatic straight, low mass tone-arm
Detachable perspex lid
Dual-specific clip-on headshell/cartridge
Anti-vibration sprung floating chassis

The CS504 was sold with a Dual cartridge which clipped onto the end to the tone-arm. Other standard cartridges can only be used with a special adaptor plate, which are now extremely rare.

FAQs

Q1. How do you get the turntable off to change the drive belt? I think mine is stuck because it won't lift off of the spindle. G. 06/10/20

Answer: Don't pull it! The CS504 has a unique system for removing the platter. First lift off the rubber mat - you will need to gently peel off the centre section which is glued on to the platter with rubber adhesive.

Then line up the platter so that the inspection holes are at Left and Right (or 9 o'clock and 3 o'clock) positions. Through the left inspection hole you will see a small brass screw head in a slot. Loosen it by a half turn anti-clockwise and then slide it to the left, as far as it will go.

Now the platter will lift up and out, including the spindle and bearing. Flip it over so that you can fit a new BELT29 on to the drive hub. Take care not to touch the bearing, except to check that it is sufficiently lubricated before turning it back over and replacing it.

Then line up the inspection hole with the speed changer and fish the belt over the motor pulley and under the speed changer arm. Give the platter a manual spin to ensure that it runs freely. Replace the rubber mat to complete the job.

If the pitch control does not work, follow the CS505 video tutorial above.
