Well, it’s a pity but it’s not the end of the world. It should be fixable. You need some good equipment to remove cp602 without lifting pads. So...
may be a long shot, but there is a switch inside the dc jack that switches between the battery power and the dc input, depending on what is...
A bad pinch roller might be hard with a glazed surface or deformed, or with small cracks. if it’s the original one it’s quite certainly bad by...
Sound like the tape is wandering around messing up the Azimut. You might need to replace the pinch roller and perhaps also adjust the Azimut...
You could trickle charge NiMH the same as NiCd, it would be much slower than an external fast charger but it would work, it's probably the best...
The walkman can charge the BP-23 internally, the middle pin in the battery "receptacle" is the charging pin, it is connected directly the positive...
