Overvoltage Repair and Prevention on an Amstrad CPC 6128

Noel's Retro Lab 10 min Published Nov 2020

About this video

Noel diagnoses an Amstrad CPC 6128 that had 12V fed into its 5V connector, finds mostly RAM chips failed, then fits a P6KE 6.8A diode to guard against a repeat.

Good to know: Soldering means burns and fumes, and old solder contains lead.

Why watch it

Anyone who swaps power supplies on a CPC may start at 06:06, where the chapters turn to preventing overvoltage. The repair and the cause each get their own chapter before that.
