A friend of mine has a Braemar tape recorder and wants to connect it to his computer so he can copy his tape recordings.

According to the 1969-1970 issue of the R+TV servicing book there is a monitor output which gives 400mV at 2K. Looking at the circuit diagram shows this output is connected to the anode of V1b (ECC83) via a 100K resistor and a 0.05uF capacitor.

If my arithmetic is right, that would give a signal of about 20 volts at the anode of V1b but it is dependant on the setting of the volume control. Does this sound about right? If so, then I presume that connecting it to the computer's line input with approx 10K input impedance would be satisfactory?

Regards,

Dave.
