Tre, The grids are closer to ground than the plates. Even though you might strive for power supplies with low impedance, the grids should be, and usually are, closer to ground. If yours are not, then maybe you should be designing circuits with lower resistance grid circuits, or using lower impedance transformers, loading the grids. The high voltage power supply is isolated from ground by high impedance, high voltage storage caps.
Especially with low mu triodes, the grids should be closer to Earth/Ground. Also, the designers of the caps did not expect you to, or want you to, get high voltage shocks. The so-called outer foil, and cap case, is to be connected to the negative end of the capacitor's circuit.
Many of the polarized caps, with one lead actually being connected to the case, were meant to be bypass caps, not coupling caps. However, many of these sure do sound great as coupling caps.
