Diamante -a discrete medium power opamp - Page 26

sonidos · 19th March 2009, 04:20 PM

I'm getting a bit confused at all the schematics listed/removed from this thread.

Can someone send me the schematic based on the final board as built by MrMajestic? I would like to build a p2p version perhaps this fall.

Thanks in advance.

Few words to thank you all !
My Diamante project is finished, it works fine and great !!!!

I've modded the gain, a lot of time to desolder 4 resistances and dismount the boards... but it worth the job !
As Aparatusonitus told I've increase the gain to 4.
R4 = 3K3 (no 3K left) and R3=1K, it's better for my HD-650.

Just built and enjoy it.
I'm not skilled, I've done it, so you can.
Thanks to all the forumers

Excellent!

I have always felt this is an excellent discrete project for people to try. It's challenging enough not to be boring, but within reach of anyone who really wants to do it.

The end result is a nice headphone amplifier/preamp.

I had mine on my desk yesterday listening to it.

Congratulations on your project! Enjoy it!

Cheers
Russ

Just found this thread!
Have the Diamantes been disc. Don't see them listed
on the left hand side on TP website.

Gee, Russ and Brian come up with some neat stuff!
I'm getting ready to try out a bunch of their Buffalo 24 boards.

It's not a product we ever sold.

There is a group buy in progress...
