gle-tube amplifier. A figure is the original radio channel audio amplifier circuit, and the other sound channel audio amplifier is increased all the way, the increase in the meta element is tube 6P1 and output transformers, as well as some resistive and capacitive elements, element costs 40 yuan. Capacitor circuit with the original Dong was omitted, the remaining elements of the numerical value by icon replacement. In addition to resistance power has marked, are selected 1/2W. Audio input can be inserted VCD players, tape deck, to close radios tuner.
