Removing the brass pulley is the easiest part in my opinion. Heating it with a soldering iron will expand it enough so it will come off easily....
Depends on the skills you have in regard to repairing motors. It's doable, but requires one to pay careful attention since motor is very small....
Welcome to the forum, @944 Dream ! You seem to be a serious collector having some very nice walkmans like: National RQ-J9, Pioneer PK-R7AW,...
Vias are plated inside, so unless you have damaged the plating soldering on the back side is enough to give electrical connection to both sides....
There's no need to move the washers slightly, as the capstan/flywheel assembly has some up/down play. That play is enough to get some oil inside....

This thread covers the repair of clutch on the AIWA Alpha-2 mechanism. This mechanism is found on the following units: HS-PX30/303, HS-PX50/505,...
My recommendation is to take things one at a time: 1. The playback level trimpots are set in a position where one cursor isn't making connection...
Let us know what the user error was, maybe someone else can avoid making it. You can't delete a thread, only admins can do that.
First method doesn't imply any risk, as you're not removing the washers. Disadvantage is oil may not get to the bottom and you also can't clean...
The mechanical auto-stop indeed only works in play. I think @Hellfire__ is reffering to the auto off function. And the problem does look like a...
BA6301 can be used as a replacement, but it would require a small custom PCB and some mods. Won't work as a plug and play solution, despite...
@Anthony I know the thread is old, but want to add some info. This unit is very possible to repair, just not the easiest one out there. First of...
There are 2 ways to do it: - either by adding oil under the washer and let it go inside the bushing; - removing the washer, taking the...
Yes there are AR-10 mechanism RQ-SX walkmans with solid capstans. In regard to mechanisms, some RQ-SX units have AR90 mechanism instead of AR10....
I mistaken this model with another one. C901 is not needed (it's there for filtering mains hum of AC adapter), as there is another capacitor at...
Since only head preamp and Dolby amp are operating on 2.8V, it makes sense the radio works without this voltage rail. Would rather suspect C901...
Apart from roughening it with ferric chloride, don't think there's much else you can do. Original micro grain surface cannot be restored. If...
In this particular case it should have been listed as "For parts or not working" indeed, my statement was generic. But it doesn't matter, fact...
