Head sits on a foil spring, so note it's normal to sit at an angle in stop, especially when door is not closed or remvoed. However if it sits at...
HF loss and imbalance are both caused by that tape curling which essentially messes up the azimuth. Head sitting at an angle (when engaged) or...
Backtension is something non-critical in compact cassette machines, since there is a pressure pad that creates tension in the tape and a good...
It's always possible to adjust by ear, but it's something I don't recommend doing as it's not an accurate method of adjusting it. Adjustment...
DDs with quartz lock always measure between 2992Hz and 2997Hz (when they work properly/have been serviced) with a tape I have recorded myself on a...
From the video it's unclear if the curl is just at the head or also at the pinch roller. It would seem like it's just at the head, but don't want...
It depends from what perspective you look at it. As far as functionality goes, it will work just fine with compact cassettes. The wow&flutter...
You need to remove the head carriage in order to replace the pinch rollers, there's not enough clearance to do it otherwise. For this you will...
AIWA did obtain very good wow&flutter figures on their high end walkmans with their original belts. Figures good enough to not really need a disc...
You need to investigate why the spindle turns slowly as that seems to be the main problem. Spindle should rotate fast 2-3 times, even if there is...
Unfortunately, in order to get a direction for the repair you need to check those things. From what I see this player is a late generation one,...
What is to be checked first on a CD player are the basics: - does the disc spin at high enough speed ? If it's rotating but very slowly there's a...
Recommend to clean the FWD/REV switch with contact cleaner (Kontakt 60). I've seen this to cause problems at times. It's located on the bottom...
Does the REV LED turn on when it switches to reverse mode ?
The one in the link looks fine to me. Any watch oil will work, you don't need anything fancy for cassette walkmans as long as it is watch oil....
Panasonic RQ-S series (first generations AR90 mechanism with pad lifter head carriage) Models affected are manufactured between 1989 and August...
Let us know what you want to know exactly about auto-reverse mechanisms. These camgear + solenoid type mechanism are pretty simple in operation:...
That is something only you can tell, but if that imbalance is not present while playing the same tape on the WM-DD33, it's pretty obvious the...
It's to be noted that most frequency response specs, at least on the lower end are not specified at -3dB. So 30Hz@-10dB for example can mean...
Battery consumption is higher during recording because of the bias oscillator, but that won't slow down the tape unless the batteries are...
