No, I suggest removing the solder bridge not the IC (hence why stating "PLL bridge"). Pin 9 should only reach 0.7-0.8V when the motor stops (no...
You need to adjust the center gear arm height in this case. This is a common problem, that's why walkman needs to be tested upside down also...
First thing I would check is what happens at pin 4 of IC5. This should stay high (3V) and be pulled low (0V) briefly only when STOP is triggered....
First thing to note is the 3V specified in the manual is with alkaline batteries, with NiMH that voltage will be a bit lower (2 x 1.2V = 2.4V)....
For WM-100/200/500 series you will need the ones at 8.34$ that has the hub sleeve only on one side not on both. The other can be modified to fit...
@Impala67 It's not the amorphous head that makes the difference, but the tape path alignment and level + bias adjustments (latter only if the tape...
Given everything works ok with the remote, the problem can't be mechanical (meaning related to mechanism). However it is possible there's too...
@Neko Prince Regarding the commutator, using a cotton swab soaked in contact cleaner or IPA is enough to clean it. For lubrication, you need...
Yes that is the intended design. Lever controlling S701 shouldn't slip when the PCB is fully pressed down. Make sure the tip of that switch is...
Can't remember for sure (didn't disassemble this reel recently), but from memory I would say it can't be pushed from the back. Don't have any...
No, the clutch disc (the part with brass "retainer") has a shaft that is pressed into the reel. Pulling the reel is the way to go, otherwise...
Yes, it will be 3 parts: the lower part of the clutch, the reel, the reel table and the spring. 4 if we consider the spring as a different part....
Indeed the method of installing is not the easiest, but would be interesting to know how the gear works. Regarding removal of clutch, the 2...
Want to make sure I understood the problem correctly. The unit does not play FWD, only REV ? And W&F is high ? Does the unit switch FWD/REV by...
Note the clutch can be disassembled from the reel easily and re-installed after the reel assy has been soaked. In my opinion it's worth trying to...
Given this only thing I can recommend is remove that camgear and lever below clutch, clean them well and re-grease. Sometimes have seen the old...
Looking at the W&F measurements, they actually don't look that bad. I expected to see something like 0.5-0.6% WRMS given the description. Average...
Ok, so first of all it's unclear what you mean by side A. It's better to reffer as FWD/REV, as a cassette can be inserted with face B up, so just...
In the video it can be seen the belt is slipping at the motor. It's also visible it's too thin, looks like a 0.6mm belt, not 0.8mm. Mechanism is...
Yes that point needs to be connected to chassis. Also, as a sidenote, that part of the flex doesn't need to be removed to service the walkman.
