Hi All

I go lower the input resistance to 100k what is used most I think.

Here I give the input tube preamp, maybe someone can give some more clearance for me I have for sure more bass and better, but I need a correction in the 30 hz range, so let me now. I don,t want use opamps I have tube hybrid design so it is a line level schematic..

Now I have a tube input with 1 meg resistor so output impedance is high, I change the resistor for 100 k now and test, I have read that output impedance may be high but input low, in my case 2k.

thanks again.
