  1. I’ve got nuthin’ on you @BearBoy. Just had a count: 86 x 74 mins and (72+40) x 80 mins.
  2. Sorry 🥸🤣 You’ve done pretty well over these years though, this is the first ‘success’ I’ve had! 😆
  3. What did you do…? 😁 20 discs I’m thinking 🤔
  4. I hope so, I just spent £92! 😆
  5. Yea just a vanilla Amazon order. No other charges - order said ‘taxes included’. The box doesn’t have a customs label so they must bulk ship the parcels by Amazon and UK customs must trust them! I just ordered one pack of 10 because I thought UK customs and ‘brokerage charges’ might get added but no. So I just ordered another 30 🤣 now I’m happy with the process. They’ll come out at £3 a piece. UK eBay for NOS is no cheaper at the moment. I’ve got a decent stock of discs although I’ve gone through quite a few recently copying CDs and recording radio programmes. 😊
  6. I thought I’d try an Amazon.co.jp purchase. Look, I know I’m way behind all you chaps… this is new territory for me! My first new-new minidiscs 😁 £3.70 ea delivered (which is a little over the £3 I try to pay for NOS) - and arrived in just a few days. Now I know this works and I don’t get scammed I might go again! 😎 Oooops…
  7. Belts are back in stock. They sell so quickly Charlie has another order in with the supplier!
  8. Quick note that Charlie is currently out of stock of this belt (15/Jan/22). I’ve dropped him a note to ask if he’s getting any more made (this was a special order belt for us folks per the thread above). Edit: Charlie got back to me within 5 minutes! 100 belts on the way to him as we speak!
  9. PCB v1 info for anyone who cares (schematic, pictures of PCB, Gerber files). SPDIF Output.pdf PCB_PCB_SPDIF Output_Top.pdf PCB_PCB_SPDIF Output_Bottom.pdf PCB_PCB_SPDIF Output_Silk.pdf Gerber_PCB_SPDIF Output.zip
  10. Sorry I didn't realise the photos were so big - shrunk them now I've managed to get on the site via a PC and Firefox (rather than on a phone). Indeed Stephen, that was the first project that made me dig into the TOSLINK circuits. This new project was originally pretty much that splitter without the input receiver and wired into the machine, but then @BearBoy and myself started discussing a coax output, so I looked into that and added one. I'm not happy with the coax RCA socket on this v1 PCB since it doesn't have any mechanical support. The one Sony use has a screw that can be used to secure it to the case for mechanical support. The one I have used relies on the solder joints to the PCB (although I did pad out a large area of copper for mechanical support). Subsequent to sending off the PCB design for manufacture, I finally tracked down the part that Sony use (attached) and found someone on eBay selling some, albeit with the black insulator rather than the usual gold/orange for SPDIF. None of the mainstream suppliers here (RS, CPC, Farnell) stock this component. I think Mouser might list the range but I didn't want to buy a thousand or have one shipped from the US at great expense. Anyway I'm in the process of redesigning the PCB for that (larger) part, but I haven't fully tested this v1 design yet, so won't order a v2 design until that's complete. Regardless, this board could actually be used sub-equipped as a single or dual TOSLINK output, and as long as your machine has SPDIF internally (which it will if it uses the Sony CXD DSP chips) and 0V and +5V then it can be fitted. The electronics is easy, it's the taking apart and drilling the back panel which is the hardest part. I have some spare v1 bare PCBs if anyone wants one to play with. I'll let you know how I get on with the v2 and if anyone is interested, give me a shout. You lot might get a little prezzie anyway for your ongoing help and encouragement! I suppose what I should do is do an "all features" PCB that can be a splitter or fitted internally to a machine with whatever combination of TOSLINK/Coax outputs you want. I guess this could end up being a bit over-engineered because the splitter needs a power supply and an input circuit whereas the output board doesn't require either. However I guess the point is I know about all of the building blocks so if you fancy something, drops some ideas around. After all these little projects come about from suggestions/ideas/threads on here! 🙂 Boy, it's great to be back... pjras1x1s_x_series_cd.pdf
  11. It has to wire into a couple of points on the main PCB (or stuffed into the ribbon cable socket before @sfbp pulls me up on that one!). The machine doesn’t need to have any digital I/O on the back panel already. I’m only really familiar with the Sony machines and it should work with any as they use the SPDIF protocol natively internally. Otherwise this PCB has the interface drive circuits so doesn’t rely on the main board having any digital outputs already.
  12. Twin TOSLINK plus coax output board. Transformer isolated coax output based on Sony MDS-E10 ‘pro’ output stage. The pulse transformer is the most expensive part by far (about 4GBP) but the PCB is padded out for a couple of options to mitigate against availability issues. This project is partially @BearBoy’s fault 😆👍 I subsequently found the part Sony use for the Coax RCA connector so I will redesign the PCB. I also missed one capacitor in the coax circuit. No real consequence but I’m a stickler for detail… I originally designed this for my MXD-D4 to provide TOSLINK output from both the CD and MD sections. However with @BearBoy’s input I added the coax output and selection jumpers so it can be used with an MD-only machine and thus add twin TOSLINK and coax outputs. Just a DIP 74HCU04 IC goes in the socket.
  13. @sfbp the third wire is probably to a temperature sensor embedded in the battery pack. This is so the charger can optimise the charge current based on the temperature of ambient and the battery during the charge cycle. This is to prolong the life of the battery and as a safety cutout.
  14. Nero is a bit clunky to use but it works. For instance it won’t access my NAS so I have to copy all the sound files to the C drive. Also understandable but annoying is it doesn’t take the title from the WAV filename, it takes it from the metadata. This means that where I have multiple instances of the same SFX, like a thunder clap (plenty of those in a Panto for the baddy) I have to go in and rename each one (since each track title includes the cue number). But the main thing is the titles seem to work reliably when dubbed to MD - both using the MXD-D4 and my existing Tascam MD-CD1 machines. So all along the problem was iTunes. I looked on the Apple forum and this issue has been reported a few of times since 2017. I tried to back date my iTunes version to before they broke it but then it couldn’t read my libraries. Stuff it! 😆
  15. I’ve been doing similar - lots of CD dubbing using my MXD-D4. I too don’t think I’ve bought anything new - but can that really be the case - there must have been something! I have bought quite a lot of used discs. if this place holds up for more than a week I’m sure I could bore you all with project updates! No major progress but all of the projects I’ve mentioned here somewhere are still in progress… oh and my ‘new’ 909 stopped reading discs 😞 and as yet despite some successful calibration runs it still won’t read ☹️ using my old faithful MZ-R700 at work again. Cut and shut MDS-E12 is still working well - it’s on my desk where I work from home. (The missus insisted my large racks went back into the shed before Christmas - well my parents did need the bedroom put back to ‘normal’ after lockdown so they could visit!). I did end up buying Nero Burning ROM (software) for writing CD-R. Finally proved iTunes doesn’t write labels correctly. Dubs from CD-R to MD always had corrupted labels. Panto cancelled here in Wales. All that music and SFX prep went to waste…
  16. Bear with us Paul, we’re not sure the site is fully working yet. Hope to be with you soon!
  17. Testing 1-2-3 from Chrome on iPhone…
  18. @sfbpCondolences and best wishes from myself and all at SIF. Take care.
  19. I think I got lucky with my MXD-D4 - I don’t think he put the model number in the title, said ‘MD and CD combo’ or something like that. Other listings for this model have silly prices. I think I’ve been lucky with all my Sony MD purchases, I haven’t paid over £100 for any of them (including the ‘pro’ ones). Did pay £120 for my Tascam MD-350 a few years back and a very silly price for my first Tascam MD-CD1 as I was desperate for a dub solution - it was the first time I’d ever seen such a machine (know better now of course, partly through this forum). I like the 3-line display on the 909 and the metal case is very nice. 🙂 I lie, my 770 was £107. Rest were max £80 I think.
  20. From your parts link, drive is MDM-7S2B which is one of many MDM7 variants using Type-S DSP CXD2664, but not one I’ve come across before. As you can see from your list MDM-7S1A is typical for MDS-JEx80 decks.
  21. See I'm too noisy. That's 3 in a row. Guess I should have done one of those fancy multi-quote things. Sorry folks 😞
  22. Ouch! How did that get past the radar? Might have had a punt on that! I've had a search logged on the 940 for a while now, but not seen anything come up at a half sensible price. I keep getting 930s and 980s. (930 looks a lovely deck but I'd want MDLP. 980 is probably lovely in truth, but I got put off that one when I saw how cheaply constructed the insides were. Probably just me being snobby...)
  23. Agree, I've had this over the past couple of weeks. Very slow/unreliable.
