Hello,
i'm getting this behaviour when playing tapes, mostly at the beginning of the tape (lasting more or less longer), where the sound level in left channel shuffle alot. it do not happens with every tape i play and of course if played with another deck, the sound is normal.
when i'm recording them to the computer, i'm getting this:

the lines you can see in the left channel is when the sound level is dropping.
any idea of what could be causing that??
