STEP 3: POWER UP PROCEDURE WITHOUT M1002 BOARDS

Identifying Defective Boards in the AP-3000 & AP-3400

Please note: All boards used in the AP-3400 are designated with an `A' suffix (e.g. M1002A) and use bright red solder mask

STEP 1: VISUAL INSPECTION OF FRONT PANEL AND FAN

a)Check to see whether the green power LED is lit. If not, the amplifier has a power supply (M1013 board), transformer, A.C. switch or line cord problem.

b)If the red protect LED stays on or samples off and on, this usually indicates a problem with one or both of the M1002 current amplifier modules and possibly damage to the M1012 voltage amplifier board.

Note: Any of the Molex cables from the M1011 circuit board to the M1012 input board as well as the M1002 current amplifiers can cause the protect LED to stay on or sample on and off. Check for misaligned pin connections or see if the ribbon cables have been cut or pinched through their insulation.

c)The fan running at full speed on power up usually indicates a problem with the fan circuitry on the M1013 board, but it can also be caused by M1011 circuit problems. Erratic fan behaviour can be caused by damaged thermistors located under the M1002 heat sinks.

d)No output on either or both channels can be caused by intermittent push switches at the input.

STEP 2: VISUAL INSPECTION OF INTERNAL CHASSIS

a)After removing the lid, look for any signs of smoke, charring or burnt components. If the M1002 boards have such damage, the M1011, M1012 and M1013 boards may also be damaged even if there is no similar charring on their components. At the least, there will be some damage to the M1011 voltage amp board in the form of blown ICs, or possibly open or shorted diodes, LEDs, resistors, transistors or capacitors. Exploded electrolytic capacitors indicate you have major repairs to the M1002, M1011 and M1013 boards.

STEP 3: POWER UP PROCEDURE WITHOUT M1002 BOARDS

It is extremely important that you never power up an AP-3000 or AP-3400 without following the procedure located on the M1011 schematic highlighted within the box drawn in dashed lines. Failure to do so will possibly result in damaging a good board. This procedure should only be done on a no load scoped output to insure the rest of the circuit boards are working before installing new or repaired M1011 modules. The output of a fully operational M1011 will give a 70V peak to peak sinusoidal (undistorted) wave form when a patch plug is attached at Pin #1. If the wave form is distorted or non- existent, or there is DC offset, do not attempt to connect any M1002 module to the M1011 or you will immediately destroy the new or repaired M1002 and will also cause more damage to the rest of the amplifier.

Note: M1002?spower supply wires (red, yellow, white, blue and black) must be removed as well as the input Molex ribbon to the M1002 when attempting to power up an M1011.

STEP 4: DISMANTLING AND REASSEMBLY PRECAUTIONS

a)When removing power supply wires or resoldering wires to eyelets on the M1011 board, double check that there are no solder bridges or icicles bridging traces or other eyelets. Failure to do so will result in the destruction of newly installed boards as well as other boards in the unit. Also make sure wire color codes are correctly oriented in their proper eyelets, and be careful that ribbon cables don?t get pinched or cut under the M1011 boards as this will result in shut down into the protect mode or even destruction of more boards.

b)When reinstalling M1002 boards, make sure the output wires, i.e. the red and yellow signal and black ground wires, are not reversed. If either channels or both are reversed, the amp will stay in protect mode with the red LED staying on or sampling on and off.
