Good on you for choosing the ampohms! Which ones did you get -- copper or tin?
As for the resistors, the one people mention most are the 499 ohm ones in the CCS boards, and some people have replaced the headphone jack resistors and the 4 grid stoppers all with 120 ohm rikens. Yes, the grid stoppers are normally 220, but 120 works fine there. I also prefer to sub Mills WWs for any sandcast resistors as I think in general they sound much cleaner, admittedly however, I have not finished my s.e.x. amp yet.
There may be others, but I'd strongly suggest just using what you have first and tweaking from there. The consensus seems to be that the majority of the resistors in this kit are quite good as they are and there is little to be gained with boutiques, and in fact there maybe voltage rating issues that you may not be aware of.
Good luck,
Jim
