This is the typical circuit of a fraction watt amplifier for a small record player or portable 70's electrola. The circuit uses germanium transistors at the output and two transformers in a class B push-pull stage. of equipment. The input is high impedance for crystal or ceramic capsules. The circuit works with 6 large batteries and has a good consumption. For recovery, use a 9 V power supply with a current of at least 1 A, as there is a small motor for the record player to power.
