Good to hear that you can pick up some work again.Thank you @WernerK, it is a pleasure to make people happy. I still could not solve one issue; some players (1,2+3) tend to jam CD's randomly between the tray and the Music Bank while all the belts were replaced and parts have been oiled according to the manual. Any idea? I have the impression it is mechanical problem rather than a problem with electronics. Currently I am doing a CD 1, which is a very nice CD player.
I have a Nak CD Player 3 that was reading the TOC but playing very raspy and distorted sound. I inspected the RF Amp board and found a bad capacitor (C213). This capacitor is 0.47uF 50V. It was reading 200pF. Replaced it and all is good now! The other caps were good but replaced them anyways. Thanks @Wolf Freudenberg !!

Anybody have a service manual for Nak CDP-2A or 2E ? (tda1541a based)
I have one on the shelf which spins out of control from the moment I turn it on.... havent been able to find the fault so had to put it away for now...

This is incredible - just yesterday I started working on my McIntosh MCD7008 (after setting it aside out of frustration) for almost a year. It would not read the CD's - ejecting them after about 20 seconds. Anyhow - after turning up the lasers power a little it began reading the discs and playing music! Only problem is the sound is a bit raspy around the edges - a problem others here have dealt with - what a blessing! I'll take @Wolf Freudenberg's advice and start replacing the indicated caps.
Good to hear BluegrassHarverst, after you replaced the caps you might need to adjust the laser power again according to the manual. In the Nakamichi manual they are referring to a formula to calculate the correct current for the laser. It is actually the first step of the manual ;-)
