87.0. "CD ON RIAA INPUT." by DRONET::SUCHAUD () Wed May 24 1989 06:00

    I give you the drawing to connect your CD on the PHONE input 
    of the preamp.
    The result sounds very good.All the details of the music are
    well amplified,stereo image is better,basses are firmlier.
    I read it in a french magazine (L'AUDIOPHILE).
    
    (I draw only one chanel)

    I would like to get your re-confirmation for the following numbers.
    
    
    1.5 micro Faraday capacitor (1.5 nF)   ?
    6.8   "      "        "     (6.8 nF)   ?
    51,000  ohm resistor        (51k  ohm) ?
    560,000 ohm resistor        (560k ohm) ?
    470     ohm resistor        (470  ohm) ?

    RE:ALL THE CAPACITORS ARE IN NANOFARAD (nF).
       FOR THE MAGAZINE,IT WAS AN OLD ONE (1984 OR 1985).

87.4Connecting CD to Radio CassetteKERNEL::ROSESat Jul 01 1989 06:1430

    I have a large radio-cassette which has Phono input sockets and
    also a DIN Input/Ouput socket. I have a CD player which I have tried
    to connect up to it. 
    
    It works O.K. when I have the leads from the CD connected to the
    DIN socket but the switch on the Radio-Cassette has to be in the
    RADIO position otherwise the sound is very distorted. The only problem
    is that with the switch in the Radio position is allows signals
    from the Radio to come through at the same time as the CD and you
    get interference.
    
    I phoned a local Audio shop to see if they would be able to do anything
    (I was hoping they could modify the PHONO input sockets) but they
    said they can't do anything. I have no electronics experience myself
    so I wouldn't know where to start.
    
    I have seen the wiring diagram on 87.0 but I wouldn't be too sure how
    to go about it. Perhaps I should take a printout of it with me to an
    audio repair shop and ask them if they can modify my Radio cassette
    PHONO input sockets or make a box which I could plug the leads into
    and then take two leads from it into the Radio cassette.

    Can anyone suggest anything. I don't particularly want to get another
    amplifier as it is only used in the Bedroom. 
    
    Thanks
