Preset Adjustment PCB 9321

To reset the amplifier bias following service or device replacement, follow these steps.

1. Before powering up the unit for the first time after replacing devices, Turn R27 andR28 (Both 1K presets) fully clockwise. This will bias the output devices into minimumconduction. Failure to do this may result in the amp appearing to draw excessivecurrent, Especially if powered through a “Current limit” device.

2. Reset amplifier DC offset by measuring between P2 (0V) and P107 (Speaker). Set to0V DC. ±±1mV, by Adjusting PS102.

3. Measure DC mV across TS109 Sense and Emitter junction. Adjust R128 until areading of 10mV ±±1mV is obtained.

4. Measure DC mV across TS105 Sense And Emitter junction. Adjust R127 until areading of 10mV ±±1mV is obtained.

5. Recheck Across TS109 as above. Reset if necessary to 10mV.

6. Double check S, E junction of all four devices (TS105,TS109,TS111,TS114) ThisShould be 10mV ±±3mV.

In practice, It may be easier to disconnect the Pre-Amp loom and facia from the rear chassis.
