I reached out to Wachara last night. He does not have like an instruction list or anything but advised me to read this:
If you have anything simpler, would appreciate you sharing with us.
Hi that article is really really good and almost a standard if there is one. I believe Wachara's builds are closer to perfection though.
You can read up any article on ESLs to understand the principle. I am away from home but will toss up links later.
In the meanwhile check Jazzman's DIY ESL. That is a whole new game altogether.
The only difference between ESLs and Estat headphones are bias voltage, size of diaphragm,spacer distance and headbands
All the very best
