Sansui BA-F1 Power Amplifier Restoration Update

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.

I will write a full piece soon, but hopefully this will whet your appetite. And a big thank you to Rob, my most patient customer, thanks mate!

Restored output amplifier module. This has blown up in the past and been put back together with half the screws missing and no heatsink paste! Both issues have now been rectified and the output devices now have nice new silicone thermal washers.

As a kid, I cherished my Tandy 200-in-1 electronics project lab, Dick Smith electronics kits, my Dad's hi-fi and my own first proper system. Later, I created Liquid Audio to help keep classic hi-fi gear alive and well. Our mission: to deliver TLC for classic Japanese, American and European hi-fi stereo equipment.
