I think it would be a good idea to obtain the schematic diagram for the television set in question before opening the cabinet and attaching the speaker leads to your stereo. Most television sets are paragons of minimalism. In quite a few cases I've seen, the speaker is driven from a single transistor class A amplifier whose Vcc is derived from 170 VDC gotten by directly rectifying the AC mains!! Be particularly suspicious if you peer inside your set and note that the speaker has a 40 ohm or greater impedance rating. If in doubt, please contact a qualified TV repair person for help: this is much more honorable than frying your TV, your stereo or especailly yourself!! Fortunately, ICs are getting to be just as cheap as transistors, thus such cost-saving measures as above are giving way more often to low voltage push-pull amps operated from safely isolated power sources.
