I’ve now finished restoring a lovely Sansui BA-F1 DC power amplifier. The Sansui BA-F1 is another beast of an amplifier from the golden era of hi-fi.
This Sansui BA-F1 has had a hard life, but will be good as new, once I’ve finished this restoration. I’m replacing all board-mounted capacitors, along with a few semiconductors. I am also cleaning and tidying up wiring and board goofs made by whoever repaired this previously.… Read more
While I am restoring this lovely AU-717 amplifier, I felt it was worth discussing the infamous Sansui corrosive glue problem.
