I modified the following circuit for a 5687 input tube followed by a 5963 output tube.

Very nice result indeed.

I rebuilt the power supply with 680uF caps and also put in 680uF output caps for the headphones bypassed with some small MKP caps.


Very impressed indeed. Nora Jones has never sounded so sweet. Bass is nice and tight with the big caps.

But I will continue to tweek values.
