[QUOTE="Moonraker, post: 1088982, member: 24248"] Thanks - interesting info! I suppose it makes sense to attempt to increase the HF cutoff of this stage, even if the amplifier is probably equipped with several triode stages anyway. The phase splitter is not normally the stage where the dominant pole is created and extending its bandwidth makes sense. However, are the advantages that great? Remember that the phase splitter gain is quite low due to local NFB and therefore the Miller capacitance is of relatively little concern. [/QUOTE]
