Hello,
i am thinking of using common power supply for main power amp and pre amp ie. both will be powered from same DC power supply source.
Heard people talking about requirement of isolation between power supply of two stages. Can't we power both the stages taking power lines from same DC power supply?
Also once we connect the pre amp to the main amp input, will both have same ground?
Also how about using isolated dc-dc converter for the preamp power supply?
thanks and regards
