Seasons greetings to all:

Am I correct when I think that the HIGH SOUNDING AUDIO from the Disc. 
needs De-Emphasis before it is fed into the transmitter to get rid of 
the background noises and high sounding audio especially on weaker 
signals?
If I have this right I would need to feed the Disc. in series with a 
a resistor then take a capicator to ground before the transmitter. 
Again if I am right what would you suggest for the starting values of 
the resistor and capicators, or what has worked pretty good as a 
standard circuit if there is such a thing. 
I have also found a circuit using a LM350 to make a DeEmphasis 
Circuit. What might this circuit do that the proper Resistor and 
Capicator Combination would not do?


Thanks guys and Happy Holidays from JIM KA2AJH in Wellsville, NY
