5687 headphone amp

Based on those numbers it's pretty clear that the 5687 is not a good choice for use this way..

Here's a thought - hybrid mu follower (pair of DN2540 or similar) using 5687 and a parafeed output transformer with a 3 - 4:1 stepdown ratio.

What's the parafeed capacitor value? Edcors are gaped.

I want to start with a simple CCS, the parafeed output capacitor if necessary & the output transformer.
