  • Two dials. Warning: The schematic is listing wrong and even non existing tube types! We are using here the standardised names. The first tube (screen grid) is shown as an indirectly heated (2.5 Volts) Tetrode, 5 pin base and top cap. There is only one such tube existing in 1929: the 24 (also under several other names like 24A, 224 etc.).The predecessor 222 was for direct heating and had a 4 pin base plus a top cap.
