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.

@ 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.

My MHMax is alive!!! And I'm very, very happy with it. It's a kit from Jeff Rossel . Thanks very much, Jeff, for that great service! These kits are very lovingly assorted. Hats off! And also thanks for all people involved in the MHMax and for shareing this knowledge. This is why I like DIY...

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...

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...

^^^^^ Oh boy, great work on perfboard! From your packing density I am miles away! Maybe I should try one time a pointed perfboard instead of my favorite stripeboard...

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...

Quote: It'll be awesome if we can use a software that actually does perfboard layout. I only use a piece of paper with little squares. , gets the job done but i'd like to have a softcopy of the layout in my pc instead of a piece of paper lol. Apart from the freeware-software posted...

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...
