    I order mine on www.safe-pcb.com, and there are a little cheaper... Very good quality for the price

    Just got the boards ! Many thanks for your work !

    To avoid the high frequency, I can add an inductor in every rail, to make a low pass filter ! The power supply doens't cost me anything, that why I use it ) If I don't have this at house, I already built the Krell one ! Build job was done by hand, I do not have specialized tools for this kind of work...

    Like said before, I have this supply at home from a previous project. I give her a try and they make the job in the right way ! I listening to the amp since 3 hours, and he is really damn good !! Absolutely no background noise, as might suggest the power supply I used... This is clearly oversized, but he accommodates well

    Yes it's 150W, 24V and 6.5A ! And there is no noise at all. I measure less than 1 mV RMS AC residue per rail... The amp is dead quiet I have this power supply from a previous project, I try it and there were just fine ...

    Here is some pics of the amp.

    I found the mistake ! He is not broken ! I have two headphones plug, one standard and one for symetric headphone. There was a mix in the output !!! That why it sound so bad and quickly go into cliping... It's much better now and he sound a lot better than my old CD player Thanks to Kevin for for his beautiful cloning !

    Thank for the tip with the sound card, I didn't think about it ! I check many time and everything is right... The amp work at low level without problem. It's only when you like to raise the volume, that it doesn't run correctly and rapidly distor ! At the beginning, the sound was awful ! But with time, he is getting far better. Just found someting strange. When I put 0.51V in the input, I have 0.56V at the output, and when I put 0.92V in the input, I have 1.00V at the output !

    I was using a old completely tweak Marantz CD-67 SE-MKII... He actually sound better than the Krell...

    I have a old generator that I've built when I was young ! I have a good scope too... A better generator can't be bad ! When I plug the generator to the amp, the input signal is getting bad I raise the supply voltage to 29V, and he always clip to earlier... Bias is set to 80mV over the 2R resistor.

    I go to buy a function generator to see how and when he clip. Like this I can measure the output power too... Any recommendation for the generator ? The amp run since 5 hours and he is getting to sound better !

    I have a OPA445 The headphone output from my old CD player is far better ! I hope that with burn in time he will get better...

    Mine actually run with +/-25V ! and I expect to rise to 28V...
