Question: my PC6 board from T4HF has the .047 caps as 0.10 caps (unless I am remembering wrong?). Is this by design? Thanks!

yes, the board works the same with the larger capacitor value

One more question, on the layout above there is a 4M7 resistor on PC6. Does that come as a 2M resistor these days? Or maybe I didn't swap the 4M7 back in after I tried the Curcio RIAA mod. I have a 2M there but wanted to go back to a stock PC6 board circuit.

it's hard to find a 4.7M resistor these days, and the 2.2M actually gives a slightly better RIAA EQ for the phono section.

roy,
In your post from 2015 regarding the layout for the PAS3 PC-6 board you state that 2 100K resistors should be changed to 95.3K. There are actually 4 100K resistors on the board. Which are to be changed?
Thanks,
Bruce

Bruce,
if you look at post 2 in this thread the parts list shows which one should be 95.3K for better phono EQ
