I have a thing for vintage test equipment, so I bought this old Eico scope from eBay. Ebay never disappoints in providing me a 'project', and I got to spend a little time diagnosing an issue with the horizontal amplifier. This video shows me trying out the scope, fixing a bad capacitor, then putting it through tests using my function generator and an Eico sweep generator, and finally doing a quick teardown.
