Took me 5 years to find decent working ones. Rare Pioneer QD-240 CD-4 demodulators i'm 'talking' about!
First one I bought two years ago from eBay. Perfectly working and tested an calibrated. Payed close to $500,- bucks for it including shipping.
When it got delivered and took it out of the box, I noticed that they had obviously switched the demodulator for a not working one with cut powercord. Whole left channel lower volume with distorted sound on, direct 2 ch phono, or auto, or CD-4 preset

I haven't had it fixed yet! It is the one on the attached photo's on top of - and now the good news - the two I bought last month the same day on ebay for plus minus $300,- a piece including shipping from two different sellers that got delivered yesterday (together with a Pioneer 600A rear amp), and actually do work as described in listing
