3、CN 收音机爱 好者资料库 RadioFans.CN 收音机爱 好者资料库 23/11/99 Issue 1 Preset Adjustment PCB 9323 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,R28,R127 and R128 (All 1K presets) fully cloc

4、kwise. 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 for Channel 1 by measuring between P2 (0V) and P107 (Speaker). Set to 0

5、V DC. 1mV, by Adjusting PS102. 3. Reset amplifier DC offset for Channel 2 by measuring between P2 (0V) and P7 (Speaker). Set to 0V DC. 1mV, by Adjusting PS2. 4. Measure DC mV across TS109 Sense and Emitter junction. Adjust R128 until a reading of 10mV 1mV is obtained. 5. Measure DC mV across TS105 S

6、ense And Emitter junction. Adjust R127 until a reading of 10mV 1mV is obtained. 6. Recheck Across TS109 as above. Reset if necessary to 10mV. 7. Check S, E junction of all four devices on channel 1 (TS105,TS109,TS111,TS114) This Should be 10mV 3mV. This completes Channel 1 re-biasing. 8. Measure DC

7、mV across TS9 Sense And Emitter junction. Adjust R28 until a reading of 10mV 1mV is obtained. 9. Measure DC mV across TS5 Sense And Emitter junction. Adjust R27 until a reading of 10mV 1mV is obtained. 10. Recheck Across TS9 as above. Reset if necessary to 10mV. 11. Double check S, E junction of all

8、 four devices on channel 2 (TS5,TS9,TS11,TS14) This Should be 10mV 3mV. This completes the amplifier re-biasing. In practice, It may be easier to disconnect the Pre-Amp loom and facia from the rear chassis. Assembly List For ( 006347 ) Preamp PCB Assembly Stock CodeItemQty Req 103815K .25W RESISTOR1
