Service position Tape Transport

picture 13

For repairs on the Tape Transport or for adjustment of the tape speed:

• Dismantle tape transport as described in

chapter 3-3.

• Fix tape transport on cabinet with one

screw as shown in picture 13.

• Connect cables on Combi Board again.

• Remove casstte door as described in chapter 3-1.

• Insert testcassette SBC420 (4822 397 30071) directly into cassette compartment and play 10kHz part.

• Adjust right hand screw for max. output and left channel = right channel.
