A bout the New RIAA
in diagram
R2(23.5k) is in series with c1(13.5nF)
But in pcb ayout.
23.5k is in series with 4.7nF
???
is this an error?

You can check it help me!
thank
I don't understand!
look at post 177
which is correct?
Is riaa circuit (top) correct
or is pcb schematic (bottom) correct?

The circuit i put the value is wrong!i check it now!
Can we agree that there are these errors one circuit? :
1) IRF9160 should be IRF9610
2) c13 + c14+c15 must be 4.7nF and NOT 13.5nF
3) c10 + c11+ c12 must be 13.5nF and NOT 4.7nF
4) number 2 and 3 must also be changed for other side of circuit?

Yes that right!
13.5nF= C10//C11//C12 (C22, C23,C24)
4.7nF= C13-C15A (C25-C27A)
Hi all!
About the cap for RIAA
Caps silver mica for RiAA, you can use the value
1. 4.7nF = 4700pF (472)
2. 13.5nf = 4700pF+4700pF+3900pF+150pF

I haven't received mine. My guess is that it is sitting in customs. Tomorrow will be 4 weeks after postage. I will start worrying after 5 weeks.

Hi Tang, and the custom is sitting in the stadium



I´m also didn´t received my boards till now.
