Hello and welcome to the forum ! The problem you have is most likely related to a tape curling at the pinch roller problem. Due to some...
Have to say I'm puzzled by the situation. The measurements look absolutely perfect, confirmed by the recorded files. Only logical conclusion I can...
For the fast forwarding issue, the problem may be a cracked gear on the mechanism. However I will need to actually see the unit to confirm this....
The voltages of the DC-DC converter are labeled on the PCB silkscreen as far as I remember, at least in some versions. For a clear reference, go...
I think it's a good idea to make recordings of the tape itself in both units, curious of the result. Also, try to see if setting the EQ to 120us...
Ok, what I can say is typically when I adjust these WM-D3s (and it's pretty typical to SONY ones in general) the right channel trimpot needs to be...
Please note the D-50 has 2 different switches that need to be closed: an open/close switch (S902) and a laser on switch (S901). If S901 is not...
I wanted to ask exactly that before my previous message, but after reading you used a pair of wireless headphones I assumed the mics are in the...
Hello and welcome to the forum ! There are a few people who can help here on the forum, including myself. What has been done on the walkman...
Hello and welcome to the forum ! You need to give us more information about the unit: - is there any noise present when it plays a cassete ? -...
When I initially looked at the diagrams realised there are quite a few parts that are not actually shown, so the diagrams are "block diagrams"...
Thanks for clarifying, @euroflash ! I agree indeed that using a full track tape for adjusting azimuth is to be preffered for the reasons you...
Ok, so first of all I will attach screenshots of the mechanism's diagrams as it will be easier to reference the parts mentioned this way. Then,...
I would check the alignment of the capstans relative to the cassette shell: remove the door, put a cassette in and observe if capstan sits...
In regard to the recording, you can get an external USB sound card with line in, like this one: https://www.ebay.com/itm/171800234043 It's enough...
Azimuth can create a slight imbalance together with high frequency loss, it depends how far off the adjustment is. In regard to the adjustment, I...
I suggest to start by looking at the block diagram signal path. From my understanding you said that the line out is fine, but you have no left...
First of all, pay attention to the fact the TC-D5M uses a center negative plug for the DC in jack. So if you are to use an adaptor, either buy one...
To me it looks like you have an azimuth problem, so I would go in that direction. First adjust by listening to see if adjusting it does actually...
Hello and welcome to the forum ! What I suggest is to check the takeup torque on both FWD and REV playback by hand. Put the walkman in play and...
