Re: Valve preamp.
I apologise for my bluntness Craig, Its just the way I express myself I guess.
I do engineer to my best standard but Im still going to be limited by the components I can source. The best capacitors I can get hold of easily are usually 1%, resistors I can get to .1%. Then when I change a valve for whatever reason it will be slightly different in performance and that will again change the error of the RIAA filter.
