    congrats GeWa! Very nice and clean work. Is the small PCB for the pot self-etched? And what transformer is that? And this is really your FIRST amp? Then I am really looking forward to see your next amps...

    After a very long timne of waiting for my Jeff Rossel kit, finally I made it. My CK²III is completed. And I must say, the sound is wonderfull! I will give him some hours of burning in and then I will try to decide which amp I love more - the CK²III or my Millett Max. I am not sure untill now.

    New Millett Hybrid Maxed Amp

    @ ruZZ.il and tomb: Thanks for the detailed calculation and for the informations on burning in. Tomb, if I understand you right you would NOT trimm the Vreg to 28VDC? Is this right? Maybe I should only be patient and wait a couple of working-hours.

    New Millett Hybrid Maxed Amp

    Hello, in the last time I built a MHMax (a kit from Jeff Rossel). Unfortunatelly Jeff shipped some wrong resistors (10k instead of 1k for RA2L/R, RA4L/R and RB1L/R). He wrote me a mail about that and was so fast in his informations that I got his mail before his kit reached me!!! He prommised...

    My first (2) DIY amps?

    hi n_maher, thanks for the tip. I thought of not useing the input caps but I was a little bit afraid of doing that. My source is a Onkyo CD-Player DX-7011 and I will now go and measure the DC-offset. I bet you are right and there will be only a few mV. And you think , SQ will improve...

    Thank you n_maher, unfortunatelly with the diamond buffers the case is now too small and the amplifier needs a recasement. But the buffers were worth the upgrade! In the next few weeks I will work on a Millet Max. A kit from Jeff Rossel is on the way...

    Hi folks, some time ago I built a PIMETA and I thought why not post here some pictures: I then built the rev. Millet Diamond Buffers and I think SQ increased audible. There is more bass and the SQ is more detailed. I'm a big fan of classical music and enjoy hearing music with...

    Danger! Do not build a blue LED VU Meter!

    Hi everybody, this is my first post here and I want first say "Hello". I think SilverTrumpet999 is absolutely right. Just for your amusement I attached two sets of spectral data, one of a blue LED and the other from a green Laser-pointer. I measured theses data myself and I think the data...
