[QUOTE="El Sid, post: 930798, member: 18550"] Thanks handsome - I wonder then if i'm not worrying too much about extremes of input? Nice tip there on load = 2-3 x Rp - where does it come from? My thinking on the low load on the preamp triode was to run it quite "hot" - I remember reading somewhere that that reduces distortion (but at the cost of valve life), and it seems to me that the lower the load resistor the lower output impedance?
