14 IELD SEICE TE : 0P & May, 00 We have experienced some failures with the short pilot runs of 0P and due to an incorrectly mounted resistor on the power board There are only about a dozen of each of these in each of our market territories These failures at first sight will seem somewhat intimidating due to the blackening soot which is produced when the resistor arcs out to the printed high voltage rails under the resistor designated 0 The damage looks far worse than it really is and is generally repairable by anyone with basic electronics and soldering skills The greatest difficulty with servicing class D amplifiers is that most service people have never serviced one before And, like all things new, they don t like being in unfamiliar water When you have done a couple of these kinds of amps, you will realize that they are probably easier to repair than their linear counterparts ut there are two dramatic differences to be observed in testing this class of amp They are: ) You cannot soft start this type of amplifier as it has an error amplifier, which will deny start up at low voltage ) You must have a load connected to the output upon startup The amp sends a test pulse upon startup which must be registered in the feedback loop before it will activate the driver chip If there is no load there is no current in the output, if there is no current, there is no voltage and consequently no feedback pulse The good news is that this class of amp will generally not cook off if you failed to repair it and then try to fire it up It usually just sits there dumbfounded waiting for you to find the missing faulty bits The process for repair of units suffering from an 0 arc over is as follows A) emove the remains of 0 and clean the soot from the board Please remember this is a doublesided circuit board with thru plated component holes Do not use excess force to remove the component leads from their solder holes They will come out easy enough when you have enough heat on the joint ) eplace the following components : ) Q, IP0 ) Q, ) U0, HC ) U, I0 And finally, 0,, which should be installed about ¼ above the board so as not to arc out to the high voltage traces again C) Measure the following parts; just to be sure we don t have any stragglers ), ohms ) 0, ), and ) D0, volt zener D) Yorkville Part # s (Q = ) (Q = 0) (U0 = 0) (U = ) (0 = 0) When all the bits have been replaced and the other parts measured, you are ready to fire it up Do not forget the startup rules mentioned above and you should have a % chance of a first shot success on the job Address any further questions to: Guy eresford (gberesford@yorkvillecom) or 0 extension
