Dimmer Touch Switch

Dimmer Touch Switch Dimmer Touch Switch circuit using TT6061A and ST136

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 […]
