STK084 Audio Amplifiers

STK084 Audio Amplifiers STK084 Audio Amplifiers circuit diagram This design is based on the 80 Watt Audio Amplifier, and was developed mainly to satisfy the requests of correspondents unable to locate the STK084 Audio Amplifiers. It uses the widespread STK084 1 IC but, obviously, its power output will be comprised in the 40W range, as […]

mayur asked: I need to design a small PCB to convert 230V AC to 24V DC, what are the main electronic components to be used? if possible provide me the circuit diagram my email is devanand_b_k@yahoo.co.in

The circuit Tv transmitter very simple

The circuit is very simple, it just has three transistors, but the transistor types have been changed for VHF/UHF transistors. You can use 2N2369, BSX19 or BSX20, or any small signal transistor with an “ft” of typically 400MHz or more. The transistor DC biasing is a little more tolerant to varying transistor types than the […]
