Practical Application – Intercom Circuit
The simple switch shown so far can be used in simple audio applications. Here is a simple “all-master” intercom circuit that steers an audio amplifier towards one of several distant receivers. All units shown are identical and are connected to the same multipair cable. One battery powers all units. You press the button corresponding to […]
Sansui 15″ CTV Model: CTVB2B15-P powersupply problem,TV not switching on,replaced C4460, issue stil persists?
Raj asked: Hi, I have a Sansui 15″ color TV Model: CTVB2B15-P. It automatically switched off. When checked, fuse was blown out, I tried replacing the fuse, but it again blown out, so suspecting the problem with SMPS, I further checked and found that C4460 transistor (or STR) was short and replaced it, and now […]
