100w amplifier

blindmole · 01:43 PM

I need a simple scheme of 100W amplifier. I have read a lot of similar themes, but I have not found anything suitable. I found a few but the reading of certain instruments are not working or bad quality.
Offer tested schemes. And cheap.
Thank you.

Look here 60-80W Power Amplifier or here http://users.tpg.com.au/users/gerskine/dxamp/ both are 100 watt amplifiers and well tested. See also this thread http://users.tpg.com.au/users/gerskine/dxamp/ .
I suggest that you search this forum and also use Google as there are many tried and tested designs out there.

What kind of power transistors can you get?

For 100W RMS into 8 ohm you need a circuit capable of running from 55v power supply rails. it will need at least 3 pairs of power transistors - perhaps two pairs of TO-3 type devices

i dont know... i am from lithuania. so i buy parts ir lithuania shops. What can you offered a lower cost. I then look in Lithuania there is an

Then your problem is getting genuine power transistors. If you cannot get genuine MJ15003/4 or MJ15024/5 transistors, then you won't be able to get 100W.

I cannot get genuine MJ15003/4 or MJ15024/5.I could not be 100W or less. maybe you can say what put in their place?
