HP 182C Oscilloscope Repair - Part 5: HP 1801A Dual Vertical Amplifier Plugin

We continue the repair of the 1801A vertical 50 MHz plug in, which we had started live during the Opensauce show. We found it had a fault in the proprietary and very mysterious delay line, and weren't sure if we could even repair it. We are going to try our best in this episode.
