Thanks for the kind offer! I am still studying the tigersaurus though. I 'll contact you when I have decided.

I built the Tigersaurus and it sounded awful. (used the SWTPC boards too.) I think that I still have the issue of Popular Electronics from the 1970's. (was it popular electronics, one of those consumer mags.)

I think you better have a look at the amp that matth built, it packs a lot of power and as he said, it is stable for pa and he actually used it for a party too.

You should get yourself BPM Studio by Alcatech, it is a full on MP3 mixing software, the MP3 engine itself runs in the kernel, so never crashes, judders etc. Then get urself a plug in USB soundcard like a Maya, that has 2 channels + out. Then all you do is plug in your 4 phono connectors into the external soundcard, plug the other end into the mixer, then you check and beatmix from the mixer. The software allows you to play 2 MP3 (or more, up to 13 I think) at the same time, and can output all of them, as long as your soundcard is up to the job. Works for me!

A problem of some sort. Probably oscillating. These amps sound absolutely killer when done right.

Mine oscillated at 2Mhz when first powered up. Sounded like an electric shaver and got real hot.

It was the solid tantalum input coupling cap.

djk,
i still have about ten sets of boards, the 40410/40409 rca transistors can no longer be found here in manila, even the shop selling them has long closed down....this amp is prone to oscilations, probably the reason for the 100ohm resistor feeding the bases of the output transistors, but even with it, there is still oscilations evidenced by power amps get hot sometimes even without signal and biasing is just right at about 50ma idle....

Yes, I built it 15 ago in a college work.

It worked fine. 360W at 8ohms load with less than .01% THD.

regards,
