CD 66 uses CDM1MKII mechanics. You have to exchanege just the laser/arm from other player. Find working CD 371 or 471 of Philips and exchange just the laser/arm. Don't exchange the PCB as there are some tricks applied by Quad and with Philips board it won't sound that good any more.

Though the laser/arm of CDM4/19 looks the same I had some bad expirences. Sometimes a good and working laser/arm of CDM4/19 don't work in CDM1MKII. The ones that always work are the whole CDM 2 family.

I have tried a CD471 and the Quad display does not function. I then replaced the laser swing arm assembly and that worked fine
