@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...

Thank you so much, @Jorge ! It's so much great information, I need some time to look at all those units. That Technics SL-XP5 is indeed to grab...
Hi Moonraker ! Please post a picture with the pinch roller and eventually make some measurements (outer diameter, height, inner diameter). It's...
I have found 2 reviews made by @walkman archive and seems that his TPS-L2 (also restored) is on par with my measurements: 0.219% WRMS....
Hello to everybody, I recently discovered my audio CD collection is starting to grow and because I like small portable devices so much (I'm...
Being honest, I did not expect that. It seems a very basic boombox. It leads to the possibilty that the original belts may be of much better...
I see. In general, I would expect decks and boomboxes to have better wow&flutter due to one particular reason: they tend to have bigger and hence...
Let me state some: the SONY WM-3, SONY WM-7, SONY WM-EX5, SONY WM-B603, AIWA HS-PC202 MKIII, Toshiba KT-4176, Toshiba KT-S3, Panasonic RQ-S25,...
