Good op amps in those. I think these can still be sent off to be repaired and upgraded. I remember running into a site that does work on them awhile back. They were branded Marantz as well. I would have one except they get top dollar and then you may need servicing. Nice score!It's a Magnavox FD-1000, which is a rebranded Philips CD-100. Found it at a hamfest several years ago for all of $10. The CDM0 transport still works fairly well, though it can be balky with CD-Rs, and it sounds pretty good. Some of the markings are worn off around the buttons, but it's in decent shape otherwise.
