Not a very helpful suggestion right now, but some 5 pin Din to phono leads and 4 pin Din to phono may be useful in testing out the Quad stuff.
If your CD has a volume control you could connect it straight to the 405 to check the power amp.

Once the power amp has been confirmed as OK, perhaps connect the 33 to it using the 4 pin Din to 4 Pin Din lead. (it is possible that you have a faulty one of these cables).

Hmm, I was wondering about the cables.
I don't think you can connect direct to the 405, without going through a pre-amp.
I'm not sure I have the ability to connect my Denon to the 405, with the Denon acting as a pre-amp.
At the moment, I only have one set of connectors.

You can test out that 4 pin din to 4 pin din lead with torch bulb and battery if you do not have a meter.

Connect one end of bulb to battery with a bit of wire, other end of battery to another wire so you have a free end.
Other end of bulb connect another wire, so you have another free end.
When both free ends are touched together, bulb lights, this gives you a continuity tester.
Check out from pin 1 of one end of Din lead to pin 1 of other end of din lead and so on.

Just looked at a cable that I use to connect 405-2 and 303 amps. Pin 4 is not used, pin 2 is earth pin 3 signal, pin 1 signal.
Pin 1 is connected to Pin 1 (at other end of lead)
Pin 2 is conn to Pin 2
Pin 3 is conn to Pin 3

Ok - cool, will try that.
Here's a photo of the back of the 405:
