So I did a little experiment of an old favourite song of mine. Here's the original wahtever I could find on YT: [MEDIA] Here's the tape version...
So I am trying to get this up on the store now, but there is a new Google Play policy that requires a closed test phase with a minimum of 12 users...
Not sure if this would be of interest to anyone or even useful, but I sometimes needed this so I made it for myself. It uses the same algorithms...
The best one I found for a walkman is the HVMLAK AIR99 -...
Also just going to leave this pic here, if anyone with a keener eye/knowledge of this board can spot something obvious that I might be missing. [IMG]
Currently the motor doesn't run at all in any mode. Pin 5 is now 0.025 V (sometimes 0.05 V) regardless of whether in play, ff, rew. In stop mode...
@Deb64 I came across some info you posted in this thread https://www.tapeheads.net/threads/wm-d6c-motor-problem.86161/ noting that pin 7 should...
Some more observations that might be useful... the voltages measured on the IC601 pins vary if I use the star point on the board vs using the...
Thanks for the follow up @Deb64. The motor running in stop mode and the random slow movement was a result of the contact cleaner. No idea why....
Pin 9 on IC601 measures 5.22 V while in play mode. I wonder if the unit is somehow permanently stuck in auto-stop mode?
Out of circuit it actually measures 10.9 uF
I tried to measure all the capacitors from C601-C613 but some didn't get a reading. I was able to get the ones below: C606: 485.1 uF - rated 10...
Sorry, found the right pins. This also measures around 9.8 kOhm and apparently, 480 uF (though I do not know how accurate this multimeter's...
Have also measured the others: C610: doesn't seem to register as anything. I.e. no measurement but also no continuity (I used the 2 points on the...
@Deb64 thanks for your reply. When I first got the walkman in March, I had used an original Sony 6V adapter that came with the walkman, it was...
@Valentin Here's the readings I got using the star point/negative battery terminal as black probe with the battery inserted and walkman in play...
Thank you, as I posted above I am not 100% sure the correct way to be measuring these. - Is it correct that I put red probe on the designated...
Ok so I desoldered the motor wires and fed it 1.5 V and I can hear it move, so the motor itself is definitely alive.
No not as yet I don't want to fully take it apart without doing some diagnostics first. I'm also not sure how much voltage to feed it.
Can someone also please confirm the correct way to read pin voltages for IC601? Is it a case of putting the device in play mode then putting the...
