  2. SONY MDS-JB940 MINIDISC PLAYER / RECORDER

    in Minidisc

    Sounds about right - just as JB980, there's a Euro model and a UK Model (except for JB980 there is no US or other model, not sure about Japanese). You can see the (service and user) manuals here.

    Your 940 does LP2 and LP4 as well (that's the Atrac3 Part - ATRAC3 refers to MDLP, not to the revision of Atrac called ATRAC 3!), the 920 does SP only.

    Thanks for your very detailed explanation. Japan were masters at creating the best of equipment but their drawback were so many models with a lot of vagueness things like brass screws etc when in reality all you ended up doing was creating a market that was so overblown that many stayed away from and never got involved at all

    sad and now today everything is revolving around the very poor quality sounding ipod

    Thanks for your replies i expect as you say theirs not much in it

    i have the MDS-JB920 uk model which is very good and hopefully this JB940 that i have just got hold of will be very similar

    I did try to get hold of a JB980 but got outbid but am learning :rolleyes:

    This model JB940 has just arrived at my home in immaculate condition and is a European model ATRAC3! my other model which is for the uk the JB920 is just wide stream they both sound the same if being honest so am pleased but if anyone could explain any differences then I'm all for learning and understanding

    Interesting. Look at this http://minidisc.org/...0LP+H300LP.html

    1. Not clear whether the H300 is the same as H300LP

    2. Looks like there is Coax in and out on the back of the one you sent link to. No mention of Coax on the MDCF page.

    Point #2 might confirm a difference....?

    All in all, a firm "I don't know".

    this thread might show some light ? it looks like the one on ebay does have both coax and optical

  6. 2 SONY REPLACEMENT NH-14WM GUMSTICK BATTERY MD Walkman

    in Minidisc

    Posted

    Most NiMH batteries need at least 3 full charge/discharge cycles before they will behave.

    Good luck!

    Many thanks for your knowledge in this field

    The Sony battery is very hard to find that and with no help in their forum it's a wonder anyone buys anything Sony in the first place there service in the UK is very poor

    Having said that the service of all the main players is poor except for denon

    In the old days I use to hang around with all of the main Japanese chairman and directors when they were in London sharing of ideas and in general promoting Hi-Fi at its very best

    Today however everything has changed the spark has gone out and the future uncertain for all of Japan which is a tragedy for all

    I just paid

    Hi Nick. Yes, usually. I have a recorder in for repair now with one of these gumsticks 'in the slot'. The top of the green outer has been cut away at the positive end, and replaced with thin insulating tape. Obviously a common problem, as I have heard of this before. The excess of plastic can prevent the contact strip making with the top of the battery - the contact comes from the side, across the thin edge and onto the contact 'pip', rather than coming at the battery from 'above' the contact, if you see what I mean. Must be very frustrating for users with no mechanical bent as they will just assume the batteries are crap and complain to the seller. And that could be another MD user lost to the iPoo.

    I have never used these batteries myself, always prefering the Pisen brand from HK.

    Jim

    hI JIM

    Thanks i wasn't sure if i should have removed the whole wrapper leaving just the bare metal or just remove just one end of the wrapper

    The battery appears to charge ok but drops a bar in the first 15 minutes so i will address this thread again at some point with my further findings

    Does anyone know what the difference is between Sony stock sold in the UK in where two models may be sold where one has a red UK badge on it with copper screws and the other no badge and ordinary screws

    My only findings over the years are the uk badged models come from a sony store and all the rest come from the likes of richer sounds etc and am told their is a sound difference in where you pay an extra

    Have you had the machine apart at all? If you have disconnected the display board, that's exactly what you get.

    The reset button doesn't really 'click' like a normal button, but it does push down very slightly, say 0.2mm?

    Thanks to Stephen I now have the AM-F80 service manual. I can confirm that NO ADJ is caused by the service adjustments not being completed, and presumably by a corrupt EEPROM too. I notice there is a main EEPROM and a secondary memory with battery backup. I assume that is for user settings such as the last track played, bass boost and so on. I doubt the EEPROM would lose it's programmed state with not being used for several years, but I suppose it is possible.

    You will need to run the adjustment routines. To be honest, I doubt you will be able to does this yourself as special tools are needed and a basic grounding on how minidisc recorders work, such as stuff like 'servo engaged', 'OWH loaded', high reflectivity and so on. We could be here until Christmas going through the procedures when I can do it in half an hour.

    Do you want to send the unit to me and I can repair, service and realign the unit? For a small fee, of course, as it is my line of business! :thank_you2:

    Jim

    no i have not touched the unit the reset button did work on pressing it to produce the no adjust error but now the reset indentation dosent work at all

    Yes please jim just let me have your address and payment details in a email and will send you a cheque

    many thanks once again

  21. Which older generation MD are good to buy?

    in Minidisc

    Posted

    Depends what you want.

    R3 is very very old, SP only. Very old version of ATRAC. Might not be pleasing.

    R91 is a fine, SP-only machine. I have one. Great for recharging gumstick NiMH batteries, too.

    R909 is MDLP (Type-R but not type-S), pre-NetMD. Basically the R900 with some things fixed. I have not had a 909 in my hands, but there are plenty who swear by it.

    Both the R91 and R909 take the "standard" sidecar that can hold an AA battery (there are a few "nonstandard" sidecars, such as the R37/50/55, and RH10/910).

    thank you :friends:

    were stuck with ipods as they are far cheaper to produce in china and most of Sony's plants are outside of japan

    There is a worldwide market for mini disc that is true but it would mean a new company starting up and going back to the way the aiwa was built. Sony has always made life difficult for it's customers in one way or another blaming the EU and although that may be true in part they could have made things better like putting a optical output on their players so that the customer could transfer his music at all time in perfect condition

    the very idea that people would abuse it i never saw that as a problem as we are awash with music from the INTERNET so who the hell would even need a copy of your music "no one"

    Sony are way to powerful a company so like apple you'll get what your given and if you don't like they couldn't care less and as i have said the ipod is so cheep to make with good profits and that is all Sony will consider at the end of day and like apple nothing else

    The sound from a ipod is well short of a mini disk and for some unknown reason the younger generation have been brainwashed by it. All of apple products have a failing be it sound or some sort of cripple that prevents it from being used in a way the customer would like and for that reason I'm out

    Good news - I have located my box of Aiwas and run through the machines. Most of them do not work, giving Caution! errors or just plain dead. Luckily one AM-F75 seems to work ok despite having a damaged jog dial. I have also found four Aiwa batteries, and have one on charge now. All I can do is charge each battery up fully, and play back prerecorded discs on shuffle repeat, to see how long the batteries last, A few cycles should give me a good idea of each one's capacity. I will let you know if any have a half-decent charge capacity in a few days time.

    Jim

    many thanks jim for your time on this matter. we still need to track down on what this error code means (no adjust) i have sent a email off to sony and hopefully but i have my doubts that they will be able to enlighten me
