line preamplifier with 6c10
hello to everyone
I have designed a line preamplifier with 6c19 because iwanted a litle gain. The rise is 120 v with load 2k. The cathode resistor i ve put 2k trimmer 1,5k parallel to regulate the milliamper. The best sound passes between 35-50 milliamper. The gains is sligntly below 2. I ve thougnt to make another for gain. I would like your opinion. somone bouilt something similar? sorre for the not so good English i |

Taki why you don't turn the schematic to SRPP instead of two common cathode stages , with SRPP you will have more gain and low output impedance , and you can lower the bias current too .
