Miller on the recieving amp stuff from the networks side and impedance on the delivering stuff, from the same right?
What is the most suitable type of resistor for R13? Metal film or wirewound?
Im thinking something like the following:
NS02B5K600FE12 Vishay / Dale | Mouser
CCF605K62FKE36 Vishay / Dale | Mouser
Regarding R14 if i change the value to 50k what difference will that make?
Im thinking of using a rhopoint 8G16D resistor but there is no 47k in farnell.
I have some welwyn rc55y 47k5 i will also try.

Both are good. Just get the better ppm one that he dimensions fit. Check that, don't force a big one that is bad for the layout, does worse than the ppm thing which at 100 and under is good enough.
50K won't matter VS 47K. Many Japanese classic integrated amps etc had 50K for mm.

Looking back you are right, he was referring to a Riaa filter resistor, not the load one. Nope, no changes there.
Hi Salas, how important are the resistors for the 2sk369bl? . I am gathering parts for the build currently. With regard to those resistors, can i use carbon resistors ( 5 percent tolerance)? . I looked at my local supplier either they don't have it or charging 30 dollars plus as it is a small order.

R2,3 you mean? Self noise is important there. Carbon is dangerous for that. I would even prefer cheap metal film 1% there over carbon, if Dale etc. aren't easily accessible.
Thank you, Salas, for the quick and comprehensive answer.
But I am lucky, Mike will provide me a perfectly matched pair for a good quadruple.
I have an unused Goldring Eroica Lo Output left over from older days. Does anybody have experience with those?
It may have been a topic already, but since the FSP is an unsymmetric circuit and the output cap is DC biased, would it not make sense to try a high quality electrolytic capacitor for C4?
I do not want to start a heretic or controversial discussion since high quality foil caps are considered to be superior in any way. But I have quite good experience with elcaps in similar situations, even non-bypassed. And I have also experience that foil caps in DC biased situations can sound more "distorted" than high quality elcaps. Any opinions?

Looking good. NOS USA Teflon even... Do those sinks have the needed mass for the output MOSFETs though? They are tall nonetheless.
P.S. See not to short any pads with the metal can C3s. Keep their barrels 1mm above board level.
