There are 5 or 6 (possibly more) slightly different motors across the EX/FX series, but all are built the same. The main difference is where the...
This thread covers how to remove the EU power limitation on SONY D-EJ250 Discman. Models sold in EU are limited to 1.5mW x 2, compared to the rest...
The EX/FX motor has magnets on both sides, but that is because the coils themselves are only PCB traces (lower number of turns), thus generating...
This thread will cover the disassembly and lubrication process of cages disc-type motors used in SONY walkmans. A short list of walkman using...
I already put the thread in the walkman repair tutorials. I will create another one with the WM-702 motor as well, as that's a bit different and...
I did edit the thread in regard to re-glueing. As of any motor of this type, yes I think re-glueing will be necessary. But I don't think it is a...
I did disassemble the motor on an EX walkman that I had handy. Created a thread about it:...
This thread will cover how to disassemble and lubricate the motor on SONY WM-EX/FX/GX series. Note that there are many types of motors used in...
I have the same suggestion I stated before in regard to the motor: try to use a plastic tool (spudger like those used to open mobile phones) to...
About the tool used to remove those cut washers, I've saw it online before. Don't know what the name of the tool is, but would like to find out. I...
Glad to see it disassembled. Given to top magnet is not part of the pulley, it can be disassembled safely. I tried to remove that part before, but...
Indeed it is a significant improvement ! However almost 0.7% WRMS is extremely high and you won't be able to use the walkman with this kind of...
Between DD22 and DD33 I would choose the DD33 as it's a better design with lower wow&flutter and much more sturdy overall build quality. The DD33...
It's hard to say for sure if it's repairable without seeing it or knowing more details. The seller states motor does not turn and LED does not...
It's only obvious if there is one. Most laptops only have a combo jack (4 pole) for MIC input and headphone output. In fact, if you think about...
Ok. So the 0.18% WRMS one is an excellent result. 0.22% WRMS one I would consider good to very good for what it is. The 0.36% can be kind of...
I have never opened an FX/EX type motor and I am not sure if they are made to be opened. As a basic concept, they look similar to the ones used in...
What software are you using in the previous post ? You are using a spectrum analysis, which doesn't reveal any figure about the wow&flutter. I...
The 2 mechanisms are the same, apart from that magnet for the hall sensor to pick up table reel rotation signal which is bigger and more elevated...
@jacobsteel I agree with what @Deb64 pointed out. In my opinion, you need to find out if wobble is from the motor itself/electronics or from the...
