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?

Yes. You cannot hook speakers directly to your player.

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?

But sometimes people like to get into a discussion, or sometimes they like
to direct questions to people they are familiar with. Sometimes they will
not take the time, or sometimes they really can't figure out what
to ask.

Sometimes you wonder.

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.

Your DVD player probably does not have a volume control, so you need an

Most DVD players DO have remote volume control capabilities by varying the

And sometimes someone new comes to a forum, asks one question that could
have been easily answered in less than it took to type it...makes a

Wasn't me; I'm not the OP.

They said "Thankyou, I would like to build an amplifier to do this but I

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.

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.)

I'll take your word for it. I'm glad all of mine do though, I use that

No apologies necessary. If you're sticking around, feel free to
contribute your experiences with whatever solution you settle on. For
myself, I've built a few chip amp kits that were reasonably simple,
efficient, decent-sounding and cheap. It's been a while though; and I
think I'd do some serious research before I went in that direction
again. There are just way too many options in ready-built amps out
there...in thrift stores, at yard sales, Craigslist etc.

FWIW, the amp module is the cheap, easy part. Building, buying or
otherwise acquiring a suitable power supply is the hard part. Iron and
copper is expensive (especially shipping). I have transformers. Either
they output too much voltage--or too little current--for the kits I want
to do.

I'm researching using the stuff I have, to do what I want: design and
build a powerful (100+ wpc) six channel power amp. It's an ongoing
project for which I have much of what I need, but.....

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.

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....

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..

Nahh...pretty simple transformers: single primary and ct secondary. 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.
