where can I get circuit diagram of color tv model videocon bazooka ?

abhay_akulkarni asked: I want circuit diagram of color tv videocon bazooka. Also some tips to trouble shoot tv problems. where can I get it?

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 […]
