Finally getting to repairing these headphones . The ESP 9 are just about done .New cushions and I put in new foam in the cans and my energizer unit had two 4uf/25v NP electrolytic caps I replaced with ES 4.7uf /50v . I'm waiting for a new AC jack(IEC) for the unit and will have to extent the headphone cord . They sound very good. Changing the foam inside the cans is a must ,the difference was amazing .
I'm doing the foam inside the 6A's now and will most likely build that T3 box , these phones seem to like the speaker terminals .
