Does a Beogram 4002 that has the optional built-in CD4 demodulator have different wires and plugs than the standard 4002?  When I used to run CD4 in the mid-70s my turntable two wires plugged into the Panasonic CD4 demodulator which then had four wires that plugged into a 4 channel preamp.  Does a CD4-capable 4002 also have four wires (plus a ground) to feed directly into a 4 channel amp?  Other than removing the top and checking for the presence of a CD4 circuit board, is there another way to positively ID a CD4 capable 4002?

All four channels are carried over in the same 5-pin DIN cable. However, the cables that actually have wiring for all four channels should be noticeably thicker. While quadraphony went out of fashion, I believe the option became more theoretic towards the end of the production run, and only 2-channel wiring may have been installed.

I think opening the top and taking a look is the only sure way to know the decoder has been installed - but the thinner cable and/or a missing "CD4" switch under the right edge should confirm it is not there!
