Dear Nordic,
I made stereo conf. on one pcb because I had a lot of grounding (and humm) trroubles with seperated design in the past.
Anyway its a long story.
And for 12v reg. output. In fact its not a regulated output its for my remote controlled input selector and motorised pot board. In fact it works with 12v AC but I will put my transformer to the outside of box so I cannot have a single transformer in the enclosure or if I dedicate a singke trafo for only motorised pot board then I will have a lot of connection between trafo box and amp. box. I hope it wont add noise to the system because of motor brushes.
Concerning the preamp supply; I expect to not need a preamp module. I will have just an input selector, a 100K motorised pot and then the amp.
Best regards,
