    AKAI 4000DS mk-II: who can help me?

    Sign in to disable this ad
    It looks like a 1/4" two-tracker. I guess I could use it for mastering, or is it a consumer reel-to-reel? It runs at 7 1/2 & 3 3/4 IPS. what can/should I do with it?

    It was my buddy's, and he doesn't know what the hell to do with it... Any ideas where I can find some basic info, like the kind of info that would be in a user's maual?... I'm not even sure how to wind the tape. what kind of tape can I use on it?

    any help would be appreciated.
    thanks

    It took 30 seconds to lift this information from the Net. Another 5 minutes of your own time on the Net and you'll have everything you need to know about a 4000DS.

    I'm almost certain that it's a quarter-track reel to reel.........a consumer-type machine. It works like a cassette on steiroids -- it records 2 tracks on one "side" of tape, and 2 more tracks on the other "side" of the tape. that way, you can play in one direction to hear one recording, and reverse the direction to hear the other "side". if you catch my drift.

    As far as recording quality goes, you can get some pretty impressive stereo recordings done with it. It's not really your BEST BET for 2-track mastering or mixing down, though. But they're sure fun to play with if you're bored.

    They're also what you'll need to use if you ever stumble across an old 4 track reel to reel album.

    Use Quantegy/Ampex 406 or equivalent tape. A new reel of that is about 12 bucks nowadays.

    The 4000DS is a consumer deck

    Single motor, belt driven, 4 track 2 channel stereo deck. My dad had the next versoin - the 4000DB which added Dolby B.

    Suitable tape would be Maxell UD, XLI or Ampex/Quantegy 407.

    Not a bad deck, will probably need the switches cleaned. If it hasn't had a huge amount of use it would work well.

    For mastering etc I'd look more towards a 2 track machine like the Tascam 32.

    hmm thanks guys... it looks like a roller (or capstan, I'm not sure which) is missing too. Overall, it doesn't look like the machine has been abused, but it hasn't been babied either. The looks look worn, but I would imagine that they still have some life in them.

    There are a bunch of these decks on ebay, and they are cheap, too, maybe I should buy another one and between the two I'll have enough parts to have a single working machine. It will be something to play with anyway, I've never used a real reel-to-reel before, so it might be useful to familiarize myself with the parts and how to wind the tape...

    Which roller? If its the small one above the large rubber roller then this is the capstan. These machines used a sleeve to change speeds - no sleeve and they ran at 3 3/4 ips, with a sleeve (which can easily go missing) they ran at 7 1/2 ips. If you look at the site that Robin gave you to Steven Bender's Akai site then I think from memory there is a link to more info about this.

    I have read conflicting stories about replacements - some sites say that the sleeve can't be replaced; that no-one has made a suitable replacement, other sites offer replacements!

    You've got to start somewhere! If the heads and mechanism are in good condition then you'll get some reasonable results out of them - I've recently played recordings made on a 4000DB in the late 70's on my Akai GX265D and they sound remarkably good!

    If you can pick up a spare machine on eBay (especially one with the capstan sleeve, if that's missing) then you'll have a good source of parts and a backup if anything does go wrong. Other 4000 series machines use the same sleeve, and from what I read the 4000DS is almost identical to the 4000DB other than the latter having Dolby.

    Have fun!

    Hi Flyer, which part is missing, the black rubber-wheel or the speed-sleeve ?
    Check the storage post located on the faceplate near headcover.
    Unscrew the nut and pull the sleeve off, install both on the capstan-axel (the axel that spins when you turn the power on, that create speed: 7-1/2 with sleeve mounted.
    If you are missing the pinch-roller I probably have a used on here.
    I have restored many 4000 models so if you need advice, parts, etc, I can help you.
    It's a consumer deck with 4-track, 2-channel stereo or mono.
    Using 7-1/2 speed and high-bias tape the quality is pretty good.
    These are hard to kill so if it looks rough, don't worry, it can fixed pretty easy without buying a second deck.


    Best regards

    See, you owe me a beer.
    Good thing it was there, now mount the sleeve on the capstan-shaft and lock down with the nut snug-fit.
    A good thing is to clean the axel first with head-cleaner as old tape-residue get stuck.
    Sleeve should slide on easy, otherwise clean again.
    Many Akai models has this sleeve, early M-series from the 60's and up to 80's
    Last one was Akai GX-4000 D.
    Here is a picture when the sleeve is mounted.
