  1. @sfbp often speaks about both of these… I need to watch this for homework! Thanks @BearBoy!
  2. Fab! If you write something maybe you’d post it on the wiki too? Add a repair section on this page: https://www.minidisc.wiki/equipment/sony/deck/mds-w1
  3. Thanks for the update and info. That is weird. I wonder if Sony had a custom part made for some reason. I’ve suspected that before - the headphone volume control on one of my MDS-E10 or E12 didn’t seem to be a standard part. That mounts to the PCB to the side so the flat on the shaft needs to be at a different position to get the knob marker to line up between the min and max position. Also I couldn’t find the correct resistance (I can’t remember now if it was 1k or 5k). For @sfbp I think the ‘L’ is maybe low profile and the ‘R’ is probably ‘regular’.
  4. Well I was musing that but I don’t see that in the data sheets. For both, CW rotation suggests A pulses before B. But that’s looking on a phone. I really want to get the two data sheets up side by side to compare…
  5. Think the difference is the PEC11 has a bushing thread and the PEC12 is non-threaded.
  6. The two encoders I bought for my Tascam MD-CD1 are: MD Pitch control: Bourns PEC12R-4230F-S0024 (=Alps EC12E24244A4), RS 781-6809 MD Jog: Bourns PEC12R-4225F-S0024, RS 781-6811 Both are 24 step with switch, D shaft (first being 30mm, second 25mm).
  7. Yea agree, don’t see anything in the data sheet. A leads B as I expected. I’ll aim to do some more research when I get on a ‘proper’ computer (rather than a phone!). I’ll dig out the part I used for my Tascam (I realise it will be different to what you likely need but it will give us a comparison).
  8. Yes it would be A and B contacts. Strange the rotation should be reversed. This will be down to which of A or B leads. Usually those two signals are 90 degrees out of phase with, I presume, A leading. How strange, but otherwise great news. Is there anything in the data sheet for the part you used that might suggest this, or that it’s something that exists as a part variant?

    480

    No didn’t entertain that guy with my cash. Have two 480’s, both a bit dodgy if I remember, I don’t use them mainstream. Main home decks are my MDS-E12, 940 from you and original 520 plus MZ-R700 at work. Three rack mount MDS-E12 (plus CDP-D12 CD) and Tascam MDCD-1 dubber for the theatre stuff.

    480

    You must be counting 480’s on two hands now! 😀
  11. Great! Please let us know how you get on and ping back if there are any other queries we might help with!
  12. Usually an Alps or Bourns and 18 or 24 pulses per rotation are usual. 24 should do it. The main issue I’ve found is finding one with the correct shaft length. I replaced one on my Tascam MD-CD1 but I’ve not needed to do a Sony. Think I got mine from RS.
  13. What’s good enough for @BearBoy is good enough for me… we’re like a pair of wide-eyed kids in a sweet shop.
  14. No not yet, been up to my eyes (and ears) with get-ins, tech and dress rehearsals. Performances this week. Maybe in the next couple of weeks when I’m over this show run.
  15. Thanks for the listing link that’s really useful. Looks like the 780 or 980 (or S500 or NT1). I was thinking about deck just for convenience so I can leave it connected up to the PC and they tend to be more robust. Maybe I should have a play with one of my portables, I’m sure I must have at least one working NetMD one!
  16. Ditto. Finding SIF works on Chrome on iPhone11, Firefox on Win10 but won't resolve ("This site can't be reached") on Chrome on Win10 (maybe I need to clear the cache or something?).
  17. TL;DR Which MD deck is the "best" for using with a Windows PC (Win10) and Web Minidisc Pro or Platinum MD apps. When I say "best" I mean the most reliable (connection and transfer) and a machine that I have a fighting chance of finding in the UK and where SP mode works well and sounds good. Those of you who frequent here will know that I do sound for a number of local theatre groups. During a performance I play music and sound effect tracks from MD using my MDS-E12 machines. Generally I will have two, one for the music (backing track) cues and one for the sound effects/incidental music and the like. The tracks are prepared on a PC with Audacity then I go through the laborious task of burning the tracks to CD-R using NeroBurning ROM, then I go downstairs and use my Tascam MD-CD1 to dub the CD-R across to each MD. Then if required I have to do some post editing on the MD - usually on the sound effects tracks - to trim them back to their required length. [Since CD enforces a minimum 4 second track length, many SFX tracks get bloated out to 4s when naturally they are 2s or less. The length needs to be trimmed (and MD will allow such short tracks) because they might need to be played back in quick succession and I don't have the time to allow that bloated track length to play the extra 2s of silence.]. Then after all of this messing about I need to listen very carefully to all of the MDs in real time to ensure nothing went haywire in all of this process and corrupted the audio or track titling - and if there is an issue I have to go back around the loop again. This is very time consuming... I'm doing this mastering process now for our panto which is coming up in early January (oh yes it is! [before @BearBoy gets me again!])... and it got me wondering, now that we have some great apps like Web Minidisc Pro and Platinum MD, could I cut out the middle-man (the CD-R) and just write the MDs directly from the PC. That would save a lot of faff... Now I know some of you are looking skyward and slapping your forehead because you have been doing just this for a long time. But you've probably been doing it with portables. But despite my rather healthy stock of MD machines I've never got into the NetMD thing. Basically because I'm more of a decks fella and I don't have a 980. So... what are my realistic options here for deck machines? And as above, ones that work with NetMD and these apps reliably... Pros/cons of each candidate machine? (I just rewatched the Techmoan video...)
  18. For completeness I’ll add his belt change video (although I think most of us here are already pretty experienced at this). Applies to most consumer and pro decks, combos and hifi units from about year 2000 since they all use one or other variant of the MDM7 drive (MDLP Type-R, Type-S and high speed dub units). I’ll add again that my preferred supplier for the belts is Charles Holt who had belts made to our spec for this drive. https://www.ebay.co.uk/itm/194744734027 See the link on the minidisc wiki repair page for the same belt change: https://www.minidisc.wiki/guides/repair/e12-belt
  19. I know exactly which screws I need to take out now 😆, which is not all of them 😆! For a 2000-era unit it seems quite serviceable. Screws rather than breakable plastic clips hold the thing together. It does still have a couple of niggles - there is a pixel row and column of the main LCD that are out and it persists on still going into demo mode (which it shouldn’t do once the clock is set!). Needs some more investigation at some point. But the MD section is fully working. 👍
  20. I’ve got it (but thank you!) but it doesn’t help much with the part ‘cos they list Sony part numbers. The info I needed is on the component (5.5V 0.22F). The order from RS arrived about half an hour ago and the unit is now fixed 😀 For anyone who cares, the RS part number is 184-5554… https://uk.rs-online.com/web/p/supercapacitors/1845554/ and I’ve got 9 spares! 😆
  21. I’ve just done a load/eject belt swap in our Sony DHC-NX5MD mini hifi. It took a disc yesterday and wouldn’t give it back! The drive is an MDM-7B, so our fave 17x0.8 belt. That all went well but I notice the machine always does an ‘Initialise’ after power has been removed. I’ve probed out the supercap and it doesn’t seem to be maintaining the backup voltage so I’ve ordered a new one (or a new 10!) from RS, so hopefully that will be here tomorrow and I’ll swap out the duff one. Hopefully that will sort the issue.
  22. Crazy days, CPC price for this case is now nearly 60 quid! They were about 27. They have 12 in stock - either they are cashing in on the popularity or ‘supply chain issues’ have put prices like this up to silly levels. It’s quiet round here, where is everyone?
  23. Just bear in mind that if the machine has been sitting around unused for some years, it might need a bit of use and button pressing and twiddling to free up the mech and clear oxidation from the contacts. Hope it starts to behave for you.
