For the price of 20 1% resistors and a plug, with no power supply needed
|
|||
|
|
you can make a D/A converter.
|
|||
|
|
|
|||
|
|
You need one plug for your amp, one for your parallel port and 9 20k and 9
|
|||
|
|
10K resistors Use 1% resistors if possible <20> and 20k sound much better than
|
|||
|
|
22k.

|
|
to be pure gold.
