HP1652B Power Inlet Repair

A few years back I bought myself a HP1652B, that’s an 80 channel logic analyser, with a two channel 100 MHz scope inside too! (Not bad for £150 eh?) In this post, I’ll cover the repair I made to the unit after it suffered a rather exciting failure. The Fault I’d been using the thing for a few months, until one day it went up in a cloud of very stinky smoke.
