In this episode Shahriar takes a look at another eBay purchase. The Associated Research Model 7854 Dielectric Analyzer was sold as a broken item. However, it was missing the critical high voltage PCB all together. Luckily, IKONIX America sells individual boards making the repair possible:

After the board replacement, the unit is up and running! AC, DC and GND tests are verified to be accurate and functional. A 1000V capacitor is pushed to failure point and the dielectric breakdown is verified by unraveling the capacitor layer by layer.
