I just bought a Sansui QRX-7500 on e-Bay recently and need to know how to set the CD-4 controls on the front panel. I'm using the Sansui with a Dual 510 CD-4 turntable and a Pickering XUV-4500 cartridge. I had a QRX-3500 and the separate QC-04 demodulator in the early 70's (used with the same Dual turntable) and I don't think I had as many things to adjust on the separate demodulator. I remember maybe a 30 KHz carrier level set and one other knob that you would adjust while playing the Sansui CD-4 Adjustment record that came with the demodulator. I remember there was a bright read carrier LED on the front of it that would go in and out if you were playing a worn out CD-4 record. My QRX-7500 didn't come with any owner's or user's manual, so I need help with this CD-4 setup subject. Also, if anyone has a copy of the user's manual that I could copy I would really appreciate it. Maybe someone has a scanned in PDF version they can share.
BTW, it's been good to find this forum. I could read the posts for hours!
