TUBE PARAMS'FEItS FOR LOW PLATE VOLTAGE
The widely used radio tubes of the AC-heater type are intended for a plate
voltage of 9Q.. 180, and 250 volts. But, in practice, cases often occur where
the radio amateur must apply considerably lower voltage (of. the order of 24--26 v)
to these tubes. Under proper conditions the tubes will give complete satisfac-
tion even at the above low values.
The table below gives the parameters of the most widely used receiver-amplifier
tubes operating on reduced plate voltages.
