回覆 (919): Test CD
I tried the test disc last weekend and I was taken by surprise to find that the 30 Hz test tone was audibly much louder than 40, in my room I mean. Yet in playing music, it's just the reverse!  
--------  
good news! you have a room mode at 30 Hz^-^  
in music, you don't get pure 30Hz signal.

If it is doubling, then it should show itself in music as well, shouldn't it?

I have the service manual with me. To be exact, there are no less than 9 checks/adjustments to be carried out everytime the laser head is replaced:  
 
Laser diode intensity check  
Servo circuit adjustment  
PLL frequency adjustment  
Sled balance  
Tracking balance  
Focus balance  
Focus offset  
Focus gain  
Tracking gain  
 
In addition, you need test disc MCD-111, frequency counter, oscilloscope, sig gen and of course the standard multi-meter.

8po, correct. That's why Limage said, '.....It involved a complex alignment procedure together with a lot of test points to ensure that the new head was up to original spec..'

Sorry sir, "ONLY" replaceable for CDP/CDT with Philips CDPRO2 mechanism only.  
 
If my memory serves me correctly, your Ensemble Dichrono CDT use Esoteric/Teac VRDS type mechanism, it's unique.....

I had the laser head of the Ensemble CD player replaced a few years ago. The replacement wasn't as simple as dissembling and assembling plus a few soldering points alone. It involved a complex alignment procedure together with a lot of test points to ensure that the new head was up to original spec. It was eventually left to the ex-distributor to work out for me at a few hundred dollars.  
 
Naturally this Pro head ought to be much more complex. What instruments do you need for proper alignment?
