In the DC-DC converters capacitor can fail, transistor and even the transformer. They can simply fail even without reversed polarity. Have you...
@Black Fingers About eccentricity, it's the rubber itself that's the problem. For example, rollers where you buy just the rubber (WM-700 series,...
The WM-30 doesn't have that switch in the jack anymore, that is only on WM-10 and WM-20 series. However it is to be noted the motor servo needs...
Swapping the rollers for new ones might seem like a logical step to do on any restoration. However, finding a good roller that's not eccentric...
Looks like it's a roller pressure related problem. Either there is not enough pressure or the roller surface is glazed and doesn't have enough...
There are a couple of possibilities (generally speaking): - there is not enough traction at the capstan/roller; This can be caused by oil...
Side A sounds really bad: lots of flutter and also muffled sound. Side B is much better in both aspects. Given the super bad flutter it is...
These last W&F figures don't look bad, especially on FWD. Variation looks a bit high, would prefer those values to be more steady. Are those max...
Thinking of it, these screws did take some persuasion to remove, but not to the point of stripping. Be sure to use a JIS screwdriver btw. As for...
Can't see anything obvious in the video. Also, given the severity of the problem, don't think the cause is something subtle like lubrication or a...
I wouldn't jump on recapping, unless there is visible leakeage. To see that you need to remove the small preamp board and check on the bottom of...
Something is likely wrong at the FWD pinch roller/capstan interface. Speed is very slow at 1975Hz (assuming the reading is correct), something...
Having 1.5V is no problem, as a fully charged alkaline would have that. So no worries there. As a sidenote, you will need new clutch gear + reel...
For sure, even compared to the previous RQ-X generation (AR20), which had a clutch retainer prohlem (and it needed to be glued), this seems to...
Do you have a WFGUI screenshot of the W&F on both side to make an idea ?
Indeed these small capacitors are harder to find nowadays, as they're less used in new designs, but can still be found at big distributors. As...
It is the first walkman featuring Dolby noise reduction indeed, it appears on a Dolby brochure (A Chronology of Dolby Laboratories 1965 - 1998) -...
Indeed SX46 is an RQ-X mechanism (AR20). As for AR10, these being late models were designed for efficiency, hence the reduced roller pressure....
I would remove that battery terminal and clean it with a wire brush in a drill or with sandpaper. It's harder to clean it in place, while...
Same sound comes from both speaker and headphone jack ?
Separate names with a comma.
