I use two paper\/oil capacitors with a total capacity of approx. 1500 \u03bcF. Thus, a capacitor voltage of 1 V is equivalent to a charge of 1.5 mAs. The time constant resulting from C and the internal resistance of the vacuum tube volt meter, VTVM (R<sub>i<\/sub>\u00a0= 11 M\u03a9), is 16500 seconds. Therefore, the capacitor voltage remains virtually constant for some time after the anode current stops flowing.
