Back by popular demand, more epic Sansui BA-5000 content!

Buoyed by the success of my Technics SE-A100 video, which now has over 22,000 views and a 98% positive rating, and needing a break from the two-day grind of producing huge articles, I decided to release another longer-form video you might enjoy. I’ve just published a deep-dive video about the incredible Sansui BA-5000 power amplifier I repaired last year.

The Sansui BA-5000 is certainly one of my favourite power amplifiers I’ve had the pleasure of working on. This video was, of course, meant to accompany my original article, but unfortunately, despite having it ready, I never got around to publishing it – until now! I’ve also updated the original article to include the video. Enjoy!
