Oracle Delphi Acrylic mat - Madrigal cartridge?

I just bought an Oracle Delphi MK III that came without a mat for the platter. How do I find one of these or is there one for sale among the audiogon crowd? The turntable has a dark brown or black cartridge with a big M on the front already. I don't know what brand of cartridge this is? My friend thinks this might be an old Madrigal cartridge. I need to set my phono stage properly and want to find out about its spec's, etc. What do you know about this cartridge? Any help would be appreciated.

Big "M". Yes, it is a Madrigal Carnegie One cartridge. This cartridge was not cheap those days.....1988-1990. I have owned on of them and did not like the sound.

Cost of the cartridge was US$690 in 1988 and recommended tracking force is 1.7 grams. I do not know the output. A good guess would be.. around 0.4mv. This is a Moving coil cartridge.

Oracle Acrylic mat can be bought directly from Oracle or from a local dealer. Cost is around $100

For a mat (the new, and better mat) contact Brooklyn Audio, through the Audiogon site. They are a Oracle dealer out of Nova Scotia. I purchased both my Oracle, and a mat upgrade from them. Or contact Oracle in Quebec 1-819-868-0284 (phone) or 1-819-868-0150 (fax). It's a great table.... Enjoy!

Genesis is right about the Carnegie, but I think it has output closer to 1mv if I remember right. A friend used one directly into the phono stage of his Conrad johnson Premeir Three. The amazing thing is that this cartridge is still intact, as I remember them being very fragile and prone to suspension or cantaliever failure. I think that was their demise, most of them crapped out in no time.
