Bases relative to ground, DC voltage.
Think selling viability was only one of many aspects, another being US having very high trade barriers on imported electronics from Japan in the...
The bases of Q302, as already stated. You will need at least a multimeter and some basic understanding of schematics (to make the correlations...
Sorry, seen now you mentioned this in first post also. Do you have any noise (hiss) that varies with volume level or nothing at all on the output...
In play you have a 10-15% increase in current draw, which is indeed on the high side (fact it's fluctuating is more of a problem). On FF/REW you...
There is only one leaf swich, muting is done by timing only on these units. Meaning the amps have a delay before they start. No muting in FF/REW....
This is the manual I have: https://elektrotanya.com/sony_wm-dd3.pdf/download.html As a sidenote, don't need to quote previous posts. Just type in...
It would be easier if you would post a picture with the wires that came off. Note the service manual does show where every wire goes on the PCB...
It's not that difficult to measure a spring: for compression springs you measure from end to end in regard to length. For extension springs,...
There are really only 3 other things that can cause increased W&F: 1. Worn capstan bushing. This is a common cause of increased W&F on belt drive...
Thinking about it, realise have seen the flywheel drive gear available online. EDIT: https://www.ebay.com/itm/166988283963 There is even a thread...
There are a couple of things that can be tried to improve the W&F on REV, although success highly depends on cause: 1. Can sand the motor spindle...
@febrice These are the BLU and WHT wires you said if you disconnect either of them you lose sound on both channels ?
Indeed all WM-150 use this type of motor. This particular unit is different than others using this mech. I was so used to the WM-150 type...
@djsubtronic What you show here is not a brushless 3 phase disc motor, but a DC motor. Opening it is completely different and more risky than the...
Do have a certain bias towards analog solutions myself, although there's nothing inherently wrong with a digital approach either. In my view...
One thing I want to add: the belts from Russell Industries are one of the best you can get. But of course the diameter has to be right: you have...
Good that you posted the video, as now I realise your initial assesment was correct. Problem is caused by a black lever from the auto-stop...
Check if the lever with lighter spring is fully coming back to resting position, that's what matters. Also if after making the lever slide...
Mechanical auto-stop isn't supposed to trigger in FF and REW, but only in PLAY. In FF/REW only electronic auto-off should work: motor stops 5...
