Assuming that your sound card has line level
inputs, you can probably connect the headphone
outputs directly to the soundcard, although
I would prefer something like this, one
for each channel

Set the volume output in your stereo system about 25% of
the way and see if the signal is large enough that you
can control it with the record level control of the
soundcard so that you reach appropriate signal levels.
The idea is to use the linear range of the amplifier
fully to maximize S/N, but not higher than that because
otherwise THD climbs up. Too bad that you don't have
a line level output.

Then, locate the loudest percussive sound in your tape,
and set the recording level as high as possible but so
that there is no clipping. Clipping is very easy to recognize
for the trained ear; just play it back and see if it is not
clipped. If you aren't sure about whether what you hear
is clipped sound or something else, you'll need to record
the excerpt several times and look at the waveform using a wave
editor (I recommend Goldwave) for evidence of
clipping. You'll soon learn to identify it.

Carlos.
