Meridian 500 Transport What transport does it use?

I think it is the CDM 4/19

Thanks Sugarbie for your input.

You can tell visually if it's a philips swing arm mechanism (CDM4 or earlier) or a linear tracker (CDM9, VAM1201). The CDM4 laser moves through an arc of a circle. Later philips transports use a worm gear to move radially across the disk.

I have heard that Meridian had to switch transport mechs. midway through the 500 series due to end of life of the older philips mechanisms. You may have to email Meridian with the serial number to get a definitive answer.

If it is a CDM4/19 then replacements are getting hard to find, so you might want to ask them, if you're planning to keep the piece.
