These old units can leak a considerable amount of current (in terms of human safety) from the power transformer to the chassis. That was mostly OK back in the day, but mixing this with newer gear that's grounded (3-wire power cord) invites catastrophe. It's all too easy to find yourself in-between the hot chassis of an older piece and the grounded chassis of modern gear. The ONLY safe solution is to add a 3-wire power cord to older gear, so that all the various chassis within the system are at the same potential. I would also recommend replacing the antenna coupling capacitor with a gimmick capacitor (many older tuners used this approach) or moving it to the secondary of the power transformer.
