I suggest trying to find them locally first, as the ones in the picturet are 6.3V rated. Those are readily available at https://www.tme.eu/. But you must check the height, as in many compact walkmans there is only space to fit the 4V rated ones (which have a height of 5mm). Don't know if the ebay seller is selling capacitors with higher voltage rating in a smaller footprint or the original ones were 6.3V rated. That needs to be checked.
Yeah this is what i want to do,try to find them locally....To get them sooner,if i cant then i will order them form ebay,i did ask the seller and he told me that they fit.A question,in the sellers pic,i see that some of the 220 6.3v red ones have different numbers,this does not matter? PS:Thank you for the useful information about the height,will be very helpful.
I bought the e bay kit from mike,I tried to find them locally but i could only find half of them.Wish me luck guys.I'm a bit nervous with the repair,i hope my technician will be able to do it properly... Placed an order with mouser,its was VERY expensive i hope it will work out fine..He said he has the 16 V ones. This is what i ordered. VS The original ones 330uf 2.5volt diameter 6.3mm length 4.2mm vs 330uF 2V 220uf 4volt diameter 6.3 mm length 3.9mm vs 220uF 4V 47uf 4volt diameter 4 mm length 4.5mm vs 47uF 4V 100uf 4volt diameter 5mm length 3.9mm vs 100uF 2V PS:Thank you Marian from fix your audio for helping me out!!!
The last update,after the fail attempts from "technicians" here the Walkman is shipped to Valentin.I wish i knew it earlier...Thank you my friend!
Will do that. There is more to be seen, the IR sensor will likely need a new LED part. Dolby levels adjusted, mech lubrication.
Sorry for the thread necro, but I just found my one of these all packed up in my mums loft. It was all there, box, headphones, 2 batteries (PB-3s) charger, AAA adapter, fake leather case and manual all from January 1990 - I have the receipt too! £91.10 bought on 13th Jan 1990 when I was 16. the batteries didn't charge - which I pretty much expected but when I put a tape in it did turn, (using Rechargeable AAA batteries) but was very very quiet. Can anyone offer any advice on how I can get this guy working again? Could the low voltage of the AAAs - 1.2v be a problem?
No, should operate on NiMH batteries just fine. Having very low volume is the typical symptom of failed capacitors. You need to replace the capacitors, values are visible in pictures. Note all of these caps are very small footprint (5mm height), so you need to order the smallest possible. SMD tantalums are an even better options as they will be easier to solder, won't fail again and are much more readily available.
I've seen the capacitor values here as well if I can't make them out https://www.stereo2go.com/topic/ind...7178235650847317&board_oid=522740502721869426 I've been reading a lot about the capacitors leaking over the circuit board and over the traces. If they have leaked, what's the best way to clean it up? Contact cleaner and a cotton bud? Also do I just dive in and start unscrewing things or what? I'm new to this sorry!!
About cleaning the leakeage, first of all you need to remove the old ones without damaging the traces. There are a few methods of doing that, what I do is add fresh leaded solder to the pads and heat them until the fresh solder starts to mix with corroded one. Of course it depends on your soldering experience, do what you feel comfortable with. Cleaning really depends on how bad the leakeage actually is. First of all you need to use some solder wick to clean all the solder from the pads (this is after old caps are removed). If it's just minor leakeage soaking a cotton swab into contact cleaner and cleaning the pads and around them will be enough. However when corrosion is really bad, what I do is soak the entire board in contact cleaner for a couple of hours and then clean it with cotton swabs (immersed in contact cleaner as well). This process may need to be repeated a couple of times if leakeage is really bad. Also switches, trimmer pots, volume potentiometer will need cleaning. As contact cleaner I recommend using Kontakt 60 (the version without added lubricant). I kind of don't see any other way than simply starting to disassemble the unit and remove the main PCB. For avoiding damage to the flex cables, I recommend to remove the PCB entirely from the unit.
