6ohm speakers and DVD player
I have a pair of 6ohm speakers (from an old stereo) which I would like
to incoprorate into a home audio system. My DVD player has a set of 5.1 output ports and I would like to connect the speakers to "front left" and "front right". The manual for the DVD player says that the audio output has an impedance of 10k ohm. Does this mean that I need an amplifier to go between the player and the speakers? |

You cannot hook speakers directly to your player. Bob Morein (310) 237-6511 Thankyou, I would like to build an amplifier to do this but I only have experience with small kit amplifiers. Can you suggest any resources to me? |

Currently my Firefox broswer has a problem with Google. Every return link goes back to Google, so I have been using yahoo, except I go back to Google often. Google does not have everything and you have to use other broswers to get more of the web. The main reason I use Google, except for the fact I started using it when most all other people were using Alta Vista ot other engines, is its selection from images to groups, etc, etc. Highly usefull. You do need to browse USENET archieves, not just the web to find information. greg |

Can you suggest any resources to me? Many amplifiers I have built are from modules. Some of the modules I have are no longer available, but 200 watts was possible from a simple circuit. If you can build small amplifiers, then you can also build large amplifiers. If you build it right with good parts from a good design, all should be fine. I would suggest buying something that allready works from Ebay. greg |

Building amplifiers has become something that people don't do so much any more, since assembly costs have gotten so low that you can probabably get one better, cheaper already built. |

Thankyou all for your pointers. I think that given the complexity of
designing an amplifier I will limit myself to kits and/or ready made amps. (Apologies to anyone who was taken aback by my original request and/or it's wording. As good as google is at finding information; searching for "build (or design) your own amplifier" throws up too many hits which say that it is too hard to do.) |

Not to mention a suitable chassis, and all the other associated hardware. Far easier to buy a cheap S/H amp IMO, and I've built my own before. Putting new modules into an amp that someone has thrown out rather than fix, can be a reasonable solution too. You often get a working pre-amp and power supply included. MrT. |

That's kind of what I've got in mind. I just need a design to match a couple of +/- 70v power supplies I have on hand. Most chip amps take +/- 45 or so.... jak |

Yep, +/- 70V is for a pretty powerful amp, not a chip amp. Can you perhaps rewire them for +/-35V instead? Will depend on how the transformers are tapped, and rectification method currently employed. Or build a high power discrete power module to make full use of the supplies.. MrT. |

I'd wanted to avoid discrete outputs based on the complexity of the number of channels I want. It might not be possible. If I find suitable chips, they'll likely be expensive enough to outweigh the convenience of building with modules. It's a long-range goal. I've gathered a goodly amount of stuff, lacking mostly the overall design and actual outputs. jak |
