DAUB D700 C SCHEMATIC - OF THIS POWER AMPLIFIER - PLEASE SEND ME !!! Good morning I am an Italian retired hi-fi repair technician, and I'd be very grateful if you could send me the wiring diagram for this powerful German power amp, which I can't find even on well-known sites like hifi engine. I'd be so happy to finally be able to repair it myself, as I've always done. I found the schematic for the smaller D500 C online, but unfortunately it's completely different from the one I need for the D700 C. My sincere, heartfelt, and heartfelt thanks to everyone in advance. Have a great day.

Try contacting the designer https://19zoll.com/en/contact-person/ Some information shows a person of the same name passed away in 2018, but there appears there are others in that organization that might assist you. Failing that , and always a good fallback ,what can be done is to reverse engineer by drawing from the pcb , the connections and parts, and arrive as best you can, its schematic. Most amplifiers follow what is called the Lin topology , and Doug Self shows that layout at 1b http://www.douglas-self.com/ampins/dipa/dipa.htm .

You can then see how and IF the Daub amplifier differs , where you then know what design traits the Daub was attempting that is different to each stage a Lin amplifier uses. Usually this is difference in current source components, noting many designs use resistive dividers, but the Daub you will find will follow many similarities.

Easy EDA can provide you ability to draw a schematic - so you can adapt from the Lin to what Daub used , and have a reference to compare each: https://docs.easyeda.com/en/Introduction/Introduction-to-EasyEDA/ A good start with Easy EDA is to use recommended parts , and then note if the Daub was peculiar in parts choices.
