@George Bond There is a tutorial for the TPS-L2 here: https://stereo2go.com/forums/threads/sony-tps-l2-wm-3-restoration-tutorial-mechanical.7123/...
@djsubtronic There are a couple of things to check: - do you have 6V at the emitter of drive transistor (Q601) ? - do you have 5.4V at the base of...
I recommend removing the whole assembly before attempting to remove the roller pin, otherwise chances are you will bend the bracket. Also note...
Listening to the recording I don't hear what I expect given the description. You stated you confirmed the very high treble with white noise test....
Chargers are not prohibeted to be shipped internationally. Indeed, I think the same as @Reli, they probably treat the charger as if it was a...
Yes, I meant autonomy, mistyped it (edited the post). The new battery is prefferable without a doubt, the Discman becomes usable with it. With...
Given on ebay shipping is listed as being from Japan, I think it's the same Japanese seller behind both listings rather than a re-sell. Seen...
In the waveform we can see how the actual speed variations look like and the frequency of variations (if it's low, high, intermittent spikes). The...
The small one goes underneath a screw that holds the PCB (where the PCB is grounded). Big one can't remember exactly where it goes, but you can...
In regard to flywheel there should be some resistnace since this is driving a geartrain + there are 2 springs (table reel and directional clutch)...
1. See picture attached. The marked flywheel has a gear which drive the bigger black gear above. Higher W&F in FWD means either that gear (or...
The FX77 uses a WM-700 series pinch roller, it's a dimension used in many SONY and quite a few other brand walkmans. This one is the roller:...
That clutch gear is available for sale new: https://www.ebay.com/itm/404445725209, https://www.ebay.com/itm/125966452808 There is also a tutorial...
Well, that's interesting. Does your takeup reel have a brass retainer or the shaft is pressed just into the plastic reel ? I asked because on all...
Glad to hear you finally found the problem ! Did you end up removing the takeup reel as well ? Ask as that's not exactly easy to do and...
The fact motor voltage is higher with load (a cassettte in) is normal, it shows the servo is compensating for the higher load, thus regulating the...
Want to add some feedback in regard to the battery in original post. In the meantime got one and tested it: compared with the 2 x 10440 cell one I...
For this particular application I think most (if not all) test tapes are ok since you won't obtain less than 0.15% WRMS even in the absolute best...
It is a significant improvement for sure. Would be curious to see a W&F reading. Note in regard to speed adjustment there's drift in this...
White lithium grease, although type of grease used on these points isn't critical.
