Says Parrand:

For storage battery tubes now in com- mercial production a resistance ranging between 25,000 and 35,- 000 ohms gives satisfactory per- forman for multistage opera- tion. One hundred thousand ohms is a satisfactory value for the present dry cell tubes and may vary between 90,000 and 120,000 ohms."
