[QUOTE="afroaudio, post: 972698, member: 15197"] I have a Sansui AU777 that has had its output transistors (Sony 2SD46 originals) replaced with modern 2N3773. Unfortunately there seems to be a low freq oscillation occurring now :( Just wondering if anyone might have in a spares bin: Sony 2SD46 or apparently these amps also left the factory with NEC 2SD188A as well later in production.
