With this new project I will try to build a high end pre-amp and hope it will outperform my Classé CP-700. I started a week ago so it is already partly assembled.
I got help on this project from the Pink Faun engineers for components and schematics. The Pre-Amp will be single ended, but this way it is more easy to afford better parts and reach the best.
The powersupply is separated in a left and right channel (which will be very very stable) and so will the Pre-Amp. The volume control they selected is a Tribute inductive control which is only 0 to 33Ohm. The transistors are specialy matched pair. The capacitors in the signal and a big pair in the power supply are Paper oil capacitors. Which will be compared with V-Caps and output transformers in a later stadium.
The biggest challenge is to cut a hole in the front for the display, but maybe I better find somebody for the milling. The display will be connected with a arduino one. The arduino will check the input voltage and protect the Pre-Amp and my speakers.
I’m planning to use a pair of XLR inputs and output so I still can use my expensive cabling. It also will have 1 or 2 RCA inputs and output for my Sub.
Please bring in your idea’s I could use all the help!
Enjoy the pictures!
