You might have seen schematics for Stereo-D/A which use
D/A-chip (or two), i designed schematic, which does not,
only 10 resistors, 2 transistors, two capacitors are needed.


 Here's the schematic :

RS232C
       1 ÄÄÄÄÄÄ 10 Kê ÄÄÄÄ¿                      
       2 ÄÄÄÄÄÄ 640 Kê Ä¿ ³  ÄEÄÄÄ¿                 
       3 ÄÄÄÄÄÄ 320 Kê Ä´ ÀB´     ³  ÄÄ TR1

       9 ÄÄÂÄÄÄ 5 Kê ÄÄÄÙ    ÄCÄÙ +  10æF

                              TR1 and TR2 are BC307 / 2SA564 or compatible.
                           ³   Use %1 or %2 resistors, it sounds much better.
                         TR 2      


NOTES :

1. When connecting to home-stereos, make sure, that you are using good cable,
   cause without that, your C0V0X will make ztrange voices during loading disk
   and starting playing!

2. Make ABSOLUTELY sure, that you have connected RS-232's pins correct!
   If you have connected them incorrectly, you can damage you system
   PERMANENTLY!

3. Do not EVER sell yuor made C0V0X to your friend or something, cause if
   errors occurs, (S)he will absolutely sure come to bark you and may want
   (a lot of) money, so (S)he can take machine to customer!
