Hello! Yes, your project is very interesting for me: I used to be fond of sound amplifiers (but they were tube monsters. Class A 10 W single-ended amplifier, can you imagine that?) I moved away from this a long time ago, but experience and knowledge remained. Let's work?

Hii, I have read your post. I think I'm the best person for it. I had previously worked on Nelson pass zen amps they are basically good quality HiFi class A amps. I can surely make one for you, And NJW1194 is a good choice for tone control. Also I had worked on AC regenerator power supply I made one for a Client for his Sound processor. Both of your requirements can be fulfilled by me. Its a very interesting project. I love to do it. Bid amount may vary upon your on project requirements. Have some queries about your project, msg me we can clear it, Thank. Looking forward to work with you! I'm Electronics Engineer, with 3+ yrs exp in circuit design, PCB layout, and product prototyping. I can make your concept into reality!

I am an electronic engineer with 20 years of experience. I've done a lot of projects so far. I use Altium in electronic design projects. I have a big library. I'm creating a schematic using the datasheet of the integrals. I know all the features of Altium. The examples are attached. I have 4 years experience in audio. I've designed an amplifier before. If you have any questions, you can ask. I fit your time and budget.
