Agree, it sounds like a VR, but if you can get them to send a piccy, there are lots of people who can help identify it, esp on the Yahoo sites.
Most people just replace the caps anyway, and there are lots of links on the site to what and where these are.
Also, if its dirt cheap, there is a vendor in the states who supplies a kit to replace the electronics with the later Audiostar. Not cheap but may be cost effective with a cheap mount.

Very simple to install, and ( with you being in Oz and a Tech ), im sure the vendor would provide info on how to test the motors first, just to ensure they are OK
