I wouldn't use that. It may be suitable for electrical stuff, but not electronics. From what is written on the can, it's a petroleum-based product...
Now I understand what is happening. The howling is either an amplifier oscillating due to a parasitic capacitance created by that residue or is...
I see nothing obvious at first glance, apart from that corrosion in the motor governor area. The capacitors do not seem to be leaky. I would...
I reported, we'll see if an admin can help. At this point I say we should keep this topic, as there are not many responses. The only 2 votes are...
Hi, Given what you're saying about the headphones getting warm and the battery terminal getting hot when plugging the jack all the way, there...
Good work, @JoFugd ! Regarding the Dolby level tape, I recommend that one because I got consistent results using it and all decks, recorders and...
I can't seem to be able to edit the response choices, only to add additional ones. Thanks for the manual for WFGUI, I was looking for it, but...
I understand, I thought you may have other belt driven units. The ones you mention all have very low wow&flutter, would guess something like 0.05%...
@CDV That's a very important point regarding the standards. For example WFGUI (that we probably all use) can measure WRMS according to DIN...
I am curious about what your opinion is regarding wow&flutter on a walkman. I started to ask myself some questions about what figure should a...
I just replaced the pinch roller on the WM-D3 in my personal collection, so decided to take additional pictures as this one has an additional...
@JoFugd You do need to repair the existing DC-DC converter. Designing a boost converter that takes 3V in and outputs 8.2V is very simple with...
I see. It would be interesting to see some pictures with the problem. Regarding the problem with the capstan, I only encountered it on belt driven...
WM-D6C Since this information is not available anywhere on the web due to the unavailability of the CX20068/CX20218 datasheet, I decided to do...
I have to say I never encountered this azimuth instability problem on SONY DD walkmans. @JoFugd Does this problem happen when you tilt the unit or...
Hi and welcome to the forum @Evilbunny ! I into designing electronics, but I am also into repairing and restoring walkmans and other vintage...
I have done some measurements for reference, as I am sure some people will want to see this. Both measurements were done on the LINE OUT to...
If you are going to buy just one, clearly the TC-D5M is the one to go for. I would choose that one especially for the build quality, it feels much...
I remember reading about a battery holder, but it is rare. I think it was sold separately from the unit itself and it's likely not that many were...
@Jorge @rcpilot23 I absolutely love these exotic colors ! White and red are particularly vibrant. There is one red D-50 on ebay ($1300...
