Hi,
Oh, well in that case I may have to scan one from my non internet computor
I did not specify output impedance but what load output can drive as I recall for this model as outputimpedance depends on setting of Volumecontrol on SBEQ.
SBEQ can drive down to 47K Ohm's
Input impedance is 500K Ohms btw
and currentdraw at 9V DC about 2mA
To set approximately flat response set Bass at 9 oc and Treble at 12 oc
That's of the top of my head
At your service
BJ
