Working on this real jerk of a Kenwood. Great amp but it suffers from a VERY intermittent problem. I can get it to crop up once every 3-5 hours for 30 seconds. Not even a consistent enough problem that I feel I could find it with freeze spray. Anyways- basically I've narrowed it down to some active component on the "driver board" which is a bit split up on this model. Well to make a long story short I'm about ready for the ol' "shotgun" method of repair at this point. Found some NOS for the FETs but now I am looking for a replacement for 2SA1125 and 2SC2633. Anyone know of a good one? This is for Q15-20 on the so called Power Supply PCB ASS'Y (x00-2010-10). The part I am working on however I assure you is a current mirror and the early stages of the driver. Thanks in advance for anyone's help on this one.
