Panasonic KXF130BX Facsimile Machine, I got this at 1995 when I started working freelance for a first time. For 21 years this working still undamaged, but I wanted for some time to do predictive maintenance, especially at the SMPS power supply.
Inspection results: Two dead capacitors at SMPS board, few with high ESR in other boards, most capacitors are good to go for another 8 years.
