Found a pair of Infinity desktop speakers at Salvation Army today that were made for IBM. Took a chance for $6 and was not disappointed.

Large drivers inside - I decided to used them as my primary desktop speaker and the “B” pair on the new Sansui.

I changed the input from the mini stereo to traditional speaker cable to connect into the Sansui. I kept the rca jack in place for the left speaker, making sure to cut the shared ground trace from the previous setup.
