Sansui BA-F1 Power Amplifier Restoration Update

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.

At 10 I was pulling apart electronics and by 13 I'd have Dad's hi-fi in pieces when my parents went out! Later, I started Liquid Audio, a specialist electronics repairer known for detail-focused service, repair and restoration of hi-fi electronics & turntables. Keeping classic hi-fi gear alive and well is what we do. Our mission: to deliver TLC for classic Japanese, American and European hi-fi stereo equipment. In my spare time, I ride motorcycles, travel, listen to music and research interesting topics.
