HI,
	I have a 13" B&W TV that has a good picture but no
audio. I checked the speaker and the switch that turns off
the sound when you have earphones plugged in. Neither of 
these are the problem. While searching the board, I was able
to find the signal across a couple of transistors, but it
is very weak. These transistors are almost directly connected
to a transformer whose secondary is basically the speaker.
	If anyone out there can give me some hints I would 
appreciate it.  I know the _BASIC_ theory of amplification,
and I am willing to try to figure out any technical explana-
tions.
				Thanx.
				Lou,
