My pleasure folks, to try schematics, to test circuits, to build them, to test them,

to publish them and to see folks building and feeling good.

This is all pleasure to me.... i love to contribute to forum folks and i love to build and listen those amplifiers, not only mine units, but i use to try other amplifiers too.

Now, the big spy, Charlie the Inspector, is building Doctor Bora circuits...always searching for good sounds, always listening and comparing and evaluating... this is pleasant to me... and the research is natural, something i have inside myself.... listening...always listening... i really do not bother to use instruments... have used them while i worked for Motorola, the VHF radios alignment had a lot of jigs and instruments...when i realised i could make 20 times faster and 5 times better listening i started the method to use "human instruments"

regards,

Carlos

What artistry. Thanks for sharing the pictures. If you have any of your power supply, I'd be interested in seeing how you did those as well.

Thanks for all the inspiration. You're truly a diy person and a credit to these forums.

best wishes,

Brian

Hey space2000, I really love the way you have mounted the output devices and veroboard. 🙂

Maybe Nordic could develop a nice small PCB for that design, then it would look schmic indeed.

A question I have is ... do your prefer the DHR sound to the Aleph amp and the Mooly amp?

thanks
🙂

hi KLe,

This three amps are totally different sound then each other. Watts makes lots of different in playing music, like comparing single and multiple violins. More watts more violins to be add. So when you will listen high watts into low volume level its sound really great.

Molly amp, hi and low are ok but the mid is not sonic and the watts are low too so can’t compare with Dx. Dx- turbo have high watts with really define music sonic. Vocal Is nice too. To my view it is Very nice amp as class AB. Molly also a nice amp but those prefer to have low watts.

Aleph-A to Z any things, They are totally different then Dx or Molly (AB). Aleph is class A so sound normally gets more open and sonic then AB. Do not expect for every thing into one amp. Molly and Dx-turbo are really cold device, its don’t run hot. Easy to build and Other hand aleph is a shara Desart, african hot or whatever you can say regarding to Hot….Hot …hot….*** sound really Hot and worm too.. Aleph is not so easy to build.

Its choice to be made which should go…..i made all of them…

Thank you.
