87.0. "CD ON RIAA INPUT." by DRONET::SUCHAUD () Wed May 24 1989 05:00

    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)

87.1	Confirmation	HGOVC::CHAKLEE	`Thu May 25 1989 19:32`	9
	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) ?
87.2	When?	HGOVC::CHAKLEE	`Thu May 25 1989 21:27`	2
	One more question. Which month's L'AUDIOPHILE?
87.3	CAPACITOR	DRONET::SUCHAUD	`Fri May 26 1989 01:07`	4
	RE:ALL THE CAPACITORS ARE IN NANOFARAD (nF). FOR THE MAGAZINE,IT WAS AN OLD ONE (1984 OR 1985). REGARDS PHILIPPE
87.4	Connecting CD to Radio Cassette	KERNEL::ROSE	`Sat Jul 01 1989 05:14`	30
	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 Trevor
