Testing 41hz AMP2 and Coldamp SPS80

Testing 41hz AMP2, a 2x300W Tripath TK2350 amplifier with Coldamp SPS80 power supply. See here how it was built:http://www.41hz.com/forums/showthread.php?3821-Building-a-tiny-2x300W-ampl­ifier-with-AMP2&highlight=sps80

Fore you folks from Germany, the video got blocked due to the very nice Eddy Vedder song playing. You can probably still watch the video by using a proxy like hidemyass....

[Veebroo]

The one in the back switches the mains and the one on the front mutes/unmutes the amplifier.

[Veebroo]

It'll certainly run fine on 35Vdc, only you need to adapt certain values for that, like voltage sensing resistors, feedback and modulator gain. I would also raise the current sensing.

If you need exact values just ask....

[Veebroo]

150W, 190W, what's the difference? If the equipment isn't handled by morons there should be no worries.

[Veebroo]

At +/-45vdc it is already producing a whopping 190W/ch under 0.1%THD+N and 220W/ch under 1%THD+N

I am using a +/-55Vdc supply here....

[Veebroo]

At what load? The fets I used in there are 75A capable, which is just monstrous!

@Veebroo Thanks

Hi. Me again. I was wondering this time on the switch(s). I am getting the one on the front, but i noted that you have a toggle on yhe baxk. I was wondering how you wired those up.

-Thanks

[bs1777]

So what do you mean ''adapt''?

[bs1777]

Well i really like to crank my shit, so im only looking for 125-150 watts RMS. So would you say a 35 volts?

[bs1777]

So to get 150w/Ch or lower, would you say a 35 or 25 volt power supply?

And is this RMS power right?
