Best supply for dac opamp supply
Hi
& found Thorsten's Loesch schematic 100 mA max,output impedance less 0,1 ohm,100 MHz opamp.& made this schema (transformer 2 15V,1000 uF BG-std,no capacitor at the output,LM329 instead TL431( Elso Kwak use them in TDA1543 schematics,what difference between TL431 and LM329?) The sound is very comfortable,no any hum. What do you think about this schematics?Does it need capacitor at the output? My dac TDA1540,i/u NOS transformer,AD797.For TDA1540 & think to try TL431 shunts and Elso Kwak triple darlington. Thanks for any suggestions. |
