498.0. "Need Audio Amp Chip for Akai 280D Tape Deck" by JAWS::COTE (Etude Brut?) Tue Sep 09 1986 13:31

    Well, of all the bad luck....
    
    Poor Edd scored a 4 track reel to reel for free. Drat!!
    
    The problem is, it needs some work. The current owner (a CSSE engineer)
    has isolated the problem as being an audio amp chip, and he has
    been unable to find a replacement at places like U-Blew-It, ect.
    
    The unit is an Akai 280D-SS. The print set lists the chip part #
    as "LD-3141". A nine pin audio amp. All nine legs on one side.
    
    Any leads to one (or four) of these beasts (or equivalent) will
    be greatly appreciated.
    
    Edd
    
    P.S. Let's see, we got the JX and now the deck.... Will someone
         please give me a 16 track mixer?

498.1Stay Active, Edd...BAILEY::RHODESTue Sep 09 1986 14:436
Sorry to hear of your gain, Edd. ;^)

Try Active Electronics in Westboro.  They are supposed to be the best 
stocked of "normal" and "weird" chips...

498.2Use a Replacement Part!CLOVAX::RATASKITom RataskiTue Sep 09 1986 14:479
    When I was working in audio repair (10-12 years ago), I replaced
    may of such critter.
    You should be able to find a cross replacement by ECG (Sylvania) 
    or SK (RCA) and if HEP (Motarola) if still around. Try your local 
    electronic supply house and they should  be able to criss-cross it 
    for you. I do mean a real wholesale electronic supply house not 
    CHIPS-R-US or what-have-you.
    
    
498.31 out, tracks are empty...JAWS::COTEEtude Brut?Tue Sep 09 1986 19:216
    ...just called Active. Hinde! Nada! Nyet!
    
    They X-reffed it to a Nu-Tone (sp?) NTE-1020 but don't carry any
    Nu-Tone chips....

    I know it sounds a bit primitive, but have you called Akai field
    service?
    
    Last time I needed one of those 9 pin SIP audio amps, it was for
    a Clarion auto power amp. I called them, and they shipped COD in
    3 days. After trying to find an equivalent at You've Done It, Horizon,
    Eli's, Newark, Gerber, and Active/Future.
    
    It's worth a try, and less of a headache than looking for substitutes.

498.6The thot plickens....JAWS::COTEEtude Brut?Wed Sep 10 1986 12:1014
    I know this sounds unbelievable, but last night I actually BOUGHT
    the unit. (Good price.)
    
    I have the print set on it. Nowhere does it give a U.S. address
    for service/parts. Can some one provide the U.S. address? The
    only address is some place in Huchicuchi, Japan....
    
    I *do* have a schematic of the chip, plus a template if
    I decide to burn my own PCB.
    
    Tom... Can you suggest a functional equivalent?
    
    Thanks

498.10Call a repair shopBARNUM::RHODESWed Sep 10 1986 17:235
Call a repair shop that repairs Akai units.
Find out how they get parts and from whom and contact them.

498.11ECG part is ObsoleteCLOVAX::RATASKITom RataskiWed Sep 10 1986 19:5014
    I checked to see what I used back when. I used an ECG part number.
    Can't find the particular ECG number now. When I look it up in the
    current ECG replacement catalog I get the nice little OBS-NLA which
    translates to OBSOLETE - NO LONGER AVAILABLE.
    
    I also checked RCA replacements. No luck. not listed.
    
    If you can find a electronic place that has had the ECG line for
    a long time (~8 yrs) they may have one laying around on the shelf.
    
    Sorry that I can't be of any more help.

498.12News flash from the Rat ShackORACLE::WATERSThu Sep 11 1986 00:3813
    By the way, folks, your neighborly Radio Shaft (or whatever you
    like to call it) now accepts orders for onesie-twosies of just
    about any semiconductor device.  They've wired themselves into
    a big replacement parts outfit, and they have the big replacement
    catalog available for your perusal in the R.S. retail stores.
    
    I haven't ordered by this method, but they claim 2 weeks turnaround,
    I think.  Of course, the part number game that you play with the
    catalog probably requires some exposure to the repair business,
    or plain old ESP.  I don't know if this service has been made
    available in all of their retail outlets yet...
