WebApr 21, 2010 · That can be a decent choice but requires quite a bit of design thought because of the high plate resistance (60-80k). If the passive RIAA build-out resistor isn’t large compared to the tube’s source resistance, the RIAA conformance will be dependent on the tube- not a good thing as tubes warm up, age, and change. http://www.diyaudioprojects.com/Tubes/RIAA-Phono-Preamp/
