Ha ha….I didn’t find them. These were purchased from a family who’s father/grandfather was buying all this stuff up from garage sales/goodwills/thrift shops in the late 90s / early 2000s. There were several storage units full of this type of stuff. Believe it or not, I did find a Sansui 9090DB (there will be a video on it someday) from a local goodwill during COVID. It wasn’t working and I picked it up for less than $10 (still has the sticker on the bottom). I think someone had picked it up from overseas, left the jumper set to 220v, and fried some resistors in the power supply. About an hour of troubleshooting and a 30 cent resistor and it’s worked for the past three years.
