RE: A tricky issue

Posted by Lew on October 12, 2010 at 22:48:33:
Thought I saw an article once in Glass Audio in which it was shown that a pair of small value resistors between the cathodes, such that the current source feeds in at the junction of the resistors rather than directly to the cathode(s), actually resulted in a reduction of distortion, at the expense of a small amount of gain. Otherwise, I am not qualified to argue. In that article, the dual-differential cascode was referred to as a "Hedge Amplifier".
