Pet Power! Transformer Restoration & Capacitor Reforming - Pet 4032

About this video

The badly rusted mains power supply of a Commodore PET 4032 is restored and its large filter capacitor is reformed, in an episode that follows a first look and disassembly.

Good to know: Mains voltage inside. Capacitors, the tube and the flyback stay charged after unplugging, the tube at high voltage. A knocked or cracked tube can implode: protect your eyes and never lift it by the neck. Old filter capacitors can smoke.

Why watch it

Capacitor reforming shares the episode with the transformer restoration, and the maker warns this is the first one cut in new editing software, so it is a bit rough.
