Fixing & Servicing a BBC Micro Power Supply after the caps explode!
About this video
Blue smoke from failed Rifa X2 suppression capacitors is the starting point for servicing a BBC Micro power supply, with the smoothing capacitors replaced using a Retro Clinic kit.
Good to know: Mains voltage inside, and capacitors that stay charged after unplugging. Soldering means burns and fumes; isopropyl is flammable. Kit comes from Retro Clinic.
Why watch it
Shown step by step, in the maker's words, from desoldering the old parts to cleaning the board with isopropyl, and the service goes beyond the X2 parts to the whole supply.
