[QUOTE="Ampdog, post: 89684, member: 144"] To deviate slightly: I have looked up the often quoted Van Waarde amplifier. Not to be purposely negative, but he is feeding his ostensibly 60 ohm headphones from an about 280 ohm source? Is this where a semi-current feed is now better than a low impedance feed? [.... apart from throttling the poor 6AS7 into a fairly non-linear region. I think you can do better than that, Karel, with all respect to VW (.... oops!)] [/QUOTE]
