Dennis,
        I just pulled out one of these caps &
connected it to a 250Vdc supply. With a resistor for
current limiting in series with the Micamold cap, the
cap draws around 1.45mA. Voltage across cap started
out at around 95 volts & has now dropped to 43 volts.
Any tube connected to this cap, especially if the
other end is grounded ( lots of 0.01uF bypass
Micamolds in the 348) will be overheated. Here goes
another few months of restoration!,
                                     Brad
