Use 6N3 electronic tube pre-prime plus feat ----- 6N3 Preamplifier

Use 6N3 electronic tube to play a proderation, 6N3 Preamplifier Keywords: with 6N3 electronic tube Use 6N3 electronic tube pre-prod with ear In order to listen to the galvans, I am equipped with a 6n3 electronic tube with a pre-level amplifier. In order to drive the headphones, add a set of completion TDA2822. The circuit cost is lower than other circuits, and it is also simple to make students or general electronic enthusiasts. The circuit is shown that the power supply is switched and inductor, and then the T1 transformer is passed through the rectifier filter, and the TDA2822 is supplied to the filament and TDA2822, T2 is connected to the T1 secondary, generate high pressure, and the high voltage power supply is supplied to 6 N3. The signal was amplified after 6N3, and the headphones were driven by TDA2822. This paper is simple, no need to debug, the parameters of the components have been indicated in the circuit diagram, and the selection of components can also be referred to other articles, and some of the preferred components are selected. This machine is particularly quiet when static is very quiet. ------------- Pull the scroll bar to view the full circuit diagram ---------------
