Before powering up the unit for the first time after replacing devices, Turn R27 and R28 (Both 1K presets) fully clockwise.

4、 This will bias the output devices into minimum conduction. Failure to do this may result in the amp appearing to draw excessive current, Especially if powered through a “Current limit” device. 2. Reset amplifier DC offset by measuring between P2 (0V) and P107 (Speaker). Set to 0V DC. 1mV, by Adjust

5、ing PS102. 3. Measure DC mV across TS109 Sense and Emitter junction. Adjust R128 until a reading of 10mV 1mV is obtained. 4. Measure DC mV across TS105 Sense And Emitter junction. Adjust R127 until a reading of 10mV 1mV is obtained. 5. Recheck Across TS109 as above. Reset if necessary to 10mV. 6. Do

6、uble check S, E junction of all four devices (TS105,TS109,TS111,TS114) This Should be 10mV 3mV. In practice, It may be easier to disconnect the Pre-Amp loom and facia from the rear chassis.
