My first lm3875
The sound is very good!
The dc offset 50mv,40mv seems too high?
Nice build, I like those chassis.
Not at all. Those values are well within the safe range.
Edit: Do you plan on picking up the "magical" resistors as recommended?
This is my test set, I'll testing Cin when my caps received , and rewire the connection , add a copper plate at the bottom.
I use Cin because : http://www.rexdiy.com/smf2/index.php?topic=432.0
The toroid is from Tamela 18v 225va.
There're some strange thing, when lm3875 turn off,I turn on the preamp, there're some loud noise from the speaker, after about 6 secs ,then dead silent.
So I turn on lm3875, and all works fine.
What do you mean the "magical" resistors ?
The TX2575, use them@Rf and R3!
