Not aware of replacements being available at this point in time. Only solution are junk donor units. But it will become a common problem in the...
Given the FF and REW buttons do lock, you are more than likely looking at a worn latch. Seen this before. Unfortunately it's something that does...
Autoreverse on this mechanism is fully mechanical. What I would check is the clutch assembly (the big black gear). Carefully remove it by...
Ok, 0.04V - 0.14V is really nothing compared to the 2.5V-3V required. What about these 2 points indicated in picture attached ? If you get...
Don't quite understand what you mean by "center reads mostly positive", it can read either positive or negative. Also please let us know what do...
Hello and welcome to the forum @leamspaceman ! If Dolby is never to be used or only B is to be used, then indeed a D6 might be the better option....
Thanks for the info ! HS-PL55/555 has the Alpha-2 mech, there are pictures with it on the linked thread. Edited the first post adding all these...
It's best to measure with a multimeter before plugging in any AC adaptor. Even safer is to simply use AA rechargables (you will need the low...
A capacitor failure is very unlikely, only situation that can cause such symptom is when a capacitor that's across the voltage rail (C309 for...
Created this thread as I need some help in creating a list with all AIWA walkmans using the Alpha-2 mechanism....
The rhytmic click sound is likely coming from the takeup reel ring gear. These type of ring gears can crack, it's a common problem on WM-10/20/30...
Apart from the belt and pulleys, would check 2 common problems on these mechanisms: 1. The main pulley: the grease on the shaft thickens, making...
Think it would be useful to post a W&F figure measured with WFGUI, so we can see the actual figure you obtained. Also, you didn't mention...
A broken clutch gear can cause a jam in the mechanism. Your camgear seems to be half-way between FWD and REV, see picture attached. From my point...
First of all, on this mechanism you will need to replace the clutch gear as a minimum, just replacing the belt won't fix it. See post #17 on this...
Want to add 3 more items on this list, which although not as common can be causes of increased W&F: 8. Too high takeup torque: this can cause the...
Panasonic RQ-X series (AR20 mechanism) These mechanisms are different than RQ-S or RQ-SX series, not sharing anything in common with them....
In regard to RQ-X units, that clutch retainer indeed does crack, as it can be seen in picture attached in first post. However, unlike RQ-SX units...
Don't know if there is a correlation between the star and type of head used. What I can tell for sure is the pointy head was also used in DC2s...
In many portable devices there's only so much space for capacitors, hence why electrolytics may not be a suitable option despite having some...
