Most modern IEMs are indeed very easy to drive, many having sensitivity specs of 106-109dB/mW (at 109 it's really sensitive). Depending on...
In the application circuit from the AN6612 datasheet the capacitor on pin 7 is 0.47μF. Looking at some other devices that use the AN6612 this...
This is a fix in the sense that it will make the walkman usable again. But the root cause of this motor hum is an aged motor as you already...
Motor is held in place by 2 screws with large head, which are probably missing in your unit. This mechanism will also need a new clutch gear...
I cannot see the image either.
I've came across this walkman a couple of times but didn't pay much attention mostly because of the boxy design and that it looked nothing really...
JVC CQ-22K/CQ-11K Mechanism is identical to the one presented in post #30 (apart from motor being in a different position), so it shares the same...
This Cybernet PS-202 is a very interesting model, I do like the color, design and the pattern on cassette door. It's pretty unique compared to the...
This mechanism has a common problem with the gears on the other side developing a hairline crack. Solution is to glue the reel shaft to the gear....
Hello and welcome to the forum, @soluna ! I think sharing pictures with the tapes you have on the forum is a very good idea. Like to see all the...
There is a thread covering a jig designed specifically to test CX20084s and see which ones work and which don't:...
The transistor was fitted before, as there is a burn mark I can see in the middle of that red glue line. The presence of the red glue is also the...
This is a good idea. Will come back with updates about this later on. The error is in the service manual itself. It's not the only one to be found...
Yes, in the WM-D6C service manual it is reversed, but on the WM-D6 manual it is drawn the correct way. The voltage divider for the negative...
It's not clear if this DC-DC converter is really different than the one in the service manual or its just a slightly different PCB layout. Note...
Hello and welcome to the forum @maximin ! I suggest starting with checking the transformer first and make sure none of the windings are open....
SONY WA-8000/WA-8200 - mechanism will need a cleaning and re-lubrication of rotating parts; - all switches will need to be cleaned with contact...
This thread covers a problem found in WM-D6/D6Cs. Problem manifests as follows: the supply reel rotates while there is no cassette inserted, but...
Glad you found the tutorial useful ! From my experience the playback levels set from the factory are off. This is what I have noticed by both...
I agree with @Emiel on this. In your picture the LEDs look much brigther than the original ones, I even see light bleeding in the counter window....
