Single Ended Triodes (SETs), the ultimate tube lovers dream.

RE: SUN SV 2A3 stereo SE amp .... MEASUREMENTS

Rage, thanks for posting the measurements.

That's quite a bit of HF roll off. It seems to me that would be audible in a way that would have a negative impact on the sound.

My educated guess as to the cause of the roll off would be the inability of the driver stage to properly drive the Miller capacitance of the 2a3.

Isn't there a driver tube that can give you the gain you require, while at the same time be able to fully drive the Miller?

From a technical POV, I would think that would give a "truer" sound.
