[QUOTE="fredeb, post: 947195, member: 13623"] ... and what phonostage and turntable do you use Ampdog ? ;D >:D I thought the 220k may lower the rp of the tube with regards to the next stage . Will a bypass cap over cathode resistor not form a type of low-pass filter combined with the grid resistor ? ( in regards to your sharp cut-off statement [member=144]Ampdog[/member] ) I'm also assuming that you're not talking about the 33pF cap . [/QUOTE]
