Sansui 881 Vintage Receiver Hum Fix

Fixing the remaining 100Hz mains hum issues the 1974 vintage Sansui 881 Receiver had. Replacing the main filter capacitors and renewing some ground connections.

Part 1 (Restoration of this receiver) is here:    • Sansui 881 Vintage Receiver Restoration  

Here's the tutorial for properly fixing the common hum issues caused by design flaws in some of the 881 receivers (there are different versions of the PCB it seems): http://conradhoffman.com/Sansui_881_m...

The capacitors I used are Mundorf Mlytic 10000uF 63V.

The tracks used for the soldering/timelapse portions of the video and testing the amp were kindly provided by Focus 10 aka Øystein Hansen. Thank you! Check out more of his work here:   / user-993847645  

Focus 10's tune "8-bit wannabe" is now also available as a single from CDBaby/iTunes/Spotify: https://store.cdbaby.com/cd/focus101
