thanks, film, not foil.

In case of removing the input cap you should check the DC-offset voltage of your amplifier. While most modern amps do have low dc-offset (less than ^ 10 mV), there might be amps with higher voltages. As the DC-resistance of the step-up trannie is rather low even a small dc-offset can make a rather high current, partially saturating the core of the transformer(s).

The frame of the es100 is not the stiffest. It is also very long, prone to vibrations.
Improvements can be made here as well but difficult without changing the original cosmetics.
The smaller es200 is much more rigid.

Default Improved new film?

What film did you use and how did you coat it?

Hi,

I used a custom made tensilized MylarŪ film of 4 micron 'thickness', proprietary fluid simply brushed on

Schematic for the ES-50. Similar and might be of use..

I think the schematic is wrong as it shows the electrical segmentation of the stators as a parallel segmentation while it is in series!

Hi,

hey Martin, havenīt You seen the 0-Ohm resistance in series? :-)
How could it be wired different?
The HT-Strip is wired directly, the midlow-strips to the left and right of the HT-strip are wired via resistor. Canīt see anything strange here.

Default Follow up question on Coating Fluid

Could you specify the fluid you used? Brand? What kind? What use is it made for? To get the correct conductivity and equally spread over the whole film is a delicate balance. Quad used a graphite powder attached to the film only by static electricity and I’m trilled to learn about a better alternative. … or is the film you are talking about conductive by itself?

Are these 2x4x47kΩ resistors metal film? If not, they are in the signal path so, it would be interesting to hear if anybody replaced them.

Nice joke about 0 resistance but I think you simply didn't understand my point.
I have seen the audiostatics from the inside myself, there is only one wire per stator (no split-up), so the different sections of a single stator are connected in series, not parallel as in the picture. I have not talked about the HT-strip. Hope you understand my point now.

Picture of a ES100 (taken from http://www.nacl.de/esl/ google image search is your friend)

From the looks of it, the circuit diagram seems to be correct.
