I need an amp,quick! How 'bout this?

iUSERTLO72p · 25th January 2008, 06:23 PM

Hi all, need an amp temporarily. What do you think of this?
http://www.electrokits.com/Audio-Amp...eap-Audio-Amp#

I have most of the parts, the person who submitted it to that site, supplied no measurements.

Can anyone help, please, or suggest any improvement?

I want to run a small sub, whilst I fix my main amp.

Last week I built a 2x25W stereo amplifier for my laptop in approx 90 minutes. I was in a real hurry, I needed something easy to carry to play ambient music in a small weekend party. I used a TDA7264 chip amp...

Oh no, not that one again....

A 100-150 watt power amp using TIP41-142-147 transistors, how about
Cheap 100 to 150 Watt Amp

Didn't think it would be discussed here, silly me.

I looked at the links, the ST151 has lots of parts. I didn't want to buy chips n things. I don't know. I'll search some more.

Thanks

Are you Mike? I still have that amp kit if you still want it. If you don't then no offence taken.

Rats, you beat me by half an hour! But I did build my own enclosure.

Sixtek's amp is about as simple as you'll get a discrete amp that is reliable. If you want simpler, pick up some LM3886's cheap on eBay and build an amp with those.

That "cheap 100-150W amp" is a dud. I tried it and it fried the 2955/3055's I used as outputs pretty much instantly (no assembly errors!). Fortunately, the loss of those was no great loss.
