The DD11 service manual specifies a wow&flutter of 0.15% WRMS. Given the similarity between DD1, DD10 and DD11, I can assume there could not be a...
From the genealogy perspective, it should be there because it is clearly related. I didn't say to remove it, just stating that in real life, it...
Given how this device is constructed, I won't consider it a DD unit, although a DD system is used, but not for driving the capstan directly....
What do you mean by off-center center gear ? Let me clarify things by stating the possibilities that I see: 1. The shaft on which the center gear...
@Raul Because the motors themselves would have to be custom made and specifically tailored to this application: very thin coils and PCB...
A perfect walkman should have the following features from my point of view: - metal case which is resistant to scratching and also can be...
@RTB It's a nice looking design ! Do you happen to have the service manual for it ? I want to check if it has a magnetic clutch and add it to the...
Can't say anything about that, as I never used Ladda. But even the genuine Eneloop Pro that I have used and use are certainly nothing spectacular...

I like how the EX-508 has its buttons on one side. It reminds me of the WM-7, which is probably one of the first full logic walkmans and also one...
I agree with the fact that grease should only be added where it was from the factory. Have seen a YouTube channel (LivingAnalog), in which the guy...
@enryfox I would take all those gears out of the mechanism, clean the shafts and inside holes of gears and then relubricate everything with oil....
What I see is interesting: so your WM-D3 did not have that hook from the factory ? I don't see any lockpaint mark on the upper carriage hook...
