@CDV You made me curious to measure it. I also have a test tape recorded on a direct drive quartz-locked deck, which I think is far from perfect...
@Boodokhan Thank you for the suggestions ! I want to make the thread more readable, as I also think it's not easy to read. Will take more pictures...
Hello Chistopher, Have you solved the problem with the capacitors ? What makes you believe they are the wrong values ? What is exactly wrong with...
ELECTRONIC ADJUSTMENTS It is critical to do the adjustments in the order presented here, as one is influenced by the other. You cannot set the...
You won't need a picture with the original idler. Mihokm is a member of this forum and his parts are very high quality and identical in shape to...
Very good point Longman ! Indeed FPGAs are not suitable for this kind of application. If one wants to build logic control to a walkman, it can be...
Hi, From what I can see in the video, the takeup reel does not turn when in play, hence the autostop mechanism engages and stops the unit. What...
I'll read it for sure, there's a lot of information in there. I did not know about it. It makes a lot more sense now: I just searched for...
[ATTACH] [ATTACH] @Mister X I did the restoration process on both, actually. I think I forgot to mention that. None of them worked initially, the...
I had no idea either, the seller sent me a different unit than the one in the pictures, but in the end I was happier with having 2 different ones....

Ok, I understand now. From what you say, it seems that the servo IC is the problem unfortunately. In which case buying a donor board or donor unit...
Maybe you do need to take the assembly out. From what the guide was showing to bend it with a small screwdriver, it seemed that it could be done...
The emitter should be battery voltage, which is 3.2V in your case. If the base voltage is 1.8-2.2V, then Ve-Vb=1-1.4V (which is Veb), whcih is...
[ATTACH] Clearly something is not right: the drop across the transistor EB junction should be between 0.6-0.8V. Did the transistor check ok with...
I would check the voltages at Q607 first: 3V on the emitter, 2.4V on the base. What is the voltage on the base of the drive transistor ?
By the looks of it, the part marked purple is the one that needs to be bent upwards. You do not need to take the center gear out to do this. Bend...
Hi, From what I see in the video it seems that the arm of the gear must be bent. Do not bend the shaft of the center gear (that is stated in the...
I did take the motor out of the bracket for bending. You need to remove 2 screws (one is the adjustment screw I wrote about) and 2 small springs...
Something I forgot to mention: that bracket only needs to be bent enough to be straight (it can be seen that now it's bent outwards) to get the...
