Still better 0.005%, I ordered mine to Michael Percy Audio, when received the resistors marked with TI 0,01%
TI mark best resistors as VAR not as TX2575

These are not simply resistors at 0.005% 0.2ppm, they are also calibration instruments.

You see, better than in spec. Do the 6.8K and the caps over to make sure.

I would also like to mention that big gains in sound quality, sometimes bigger than fancy components on the RIAA, can be gained by clean records!
I can't imagine how I could live so long without a record cleaning machine!

See the small bump at 1hz... it can be cured by lowering the 6790r to 6775 (with some megas in //)

It must sound spectacular as is anyway

Thanks again Ricardo.
Will check actual values again, but not before Monday and correct if necessary.
