I managed to swap some components last night. I tried both 10uf at c707 and 47k at r726 and no real change. I don’t think q715 was switching at...
Thank you Valentin! This is extremely helpful. R726 is reading 100k in circuit but I agree, the voltage drop is not as expected so I may try...
Thanks so much for the response Valentin. I may actually have a solenoid I could try - let me check. I assumed it was OK since it worked with a...
Ok, some observations I made on the last transistor that controls the solinoid. The yellow is the base and the blue is the collector. On the...
Hi, I thought I would bump this up before it gets buried too deep. If anyone has any thoughts, that would be much appreciated. I will continue...
Hi, I am working on a nice F100III and was hoping to get some much appreciated help from some schematic experts. The unit is serviced/working...
Ok, fair enough. From the videos it does seem that it does slow down when upside down and then the speed increases as you flip it back (although...
I have worked a number of these and this can be tricky. It does sound to me that the motor is struggling a bit even when you first hit play. I...
I would like to share a some observations on pinch rollers for the WM-100/200/500 series. I have worked on a number of these and there is often...
Success! I picked up 0.1mm on Amazon and wound it up. It is spilling over the channels a bit so 0.07mm would be better. I did 12.5 turns as...
Ok, I just took it apart and I think you are right! 12.5 turns (as it goes to the other side), wire is 0.07mm it seems. I think I can rebuild...
Thank Valentine, sorry for the delayed response but I stopped working on this one (budget unit). I hope to get back to it and check the motor...
[ATTACH] [ATTACH] [ATTACH] Hi everyone, it looks like 2 of the channels on this 3 channel choke (L14) are open circuit on this Aiwa J202MkIII. I...
Some great units for sale, check out @ff.play.rew on instagram for current inventory....
Hi everyone, I am working on a f2068. It is a fairly budget model but I thought I would ask before abandoning the project. The unit is in...
Thanks! I will do the same. Jehr
Hi everyone, I have started a new Instagram page with some of my Walkman projects/repairs and other retro-tech stuff. Checkout/follow...
Hi, is there a search FAQ for the forums? Maybe it’s just me, but I try to search on WM-2 and it says the term is too short. If I add WM-2...
Thanks Squiggly. I appreciate all the detail on this. I will do some voltage measurements and report back. I did replace the 220uf near the...
Thanks Valentin and Squiggly, I appreciate your comments here. I put new rollers on and it helped but most of the issues appear to be some...
