When connected to the "A" battery this new Balkite Combination Radio Unit supplies automatic power to both "A" and "B" circuits. Controlled by the filament switch on your set. Entirely automatic in operation. Can be put either near the set or in a remote location. Will serve any set now using either 4 or 6-volt "A" batteries and requiring not more than 30 milliamperes at 135 volts of "B" current — practically all sets of up to 8 tubes. Price $59.50. (In Canada $83.)

The light socket is your most convenient source of radio power. Use it by adding the new Balkite "B" and the Balkite Trickle Charger to your radio set.
Balkite "B"— the unique "B" power supply— eliminates "B" batteries entirely and supplies "B" current from the light socket. The new Balkite "B"-W at $2750* serves any set of 5 tubes or less requiring 67 to 90 volts. Balkite "B"-X at $42* serves sets of up to 135 volts and 8 tubes. Balkite "B"-Y at $69 serves any standard set.
The Balkite Trickle Charger at $10* is probably the most popular of all chargers. Over 200,000 were purchased during one season and are now in service. Instead of operating intermittently at a high rate, it operates continuously at a low rate, thus automatically keeping the battery at full charge. In effect it converts your "A" battery into a light socket "A" power supply. With
