Does anyone have interelectrode capacitance specs/measurements for the EML 20A to calculate Miller capacitance? Unfortunately it’s not included on the product page of their website.
You can measure it. Build a simple stage and measure the high freq cut off frequency.
Then do the same with a 100k or 1M series R to the grid. The response will drop at a much lower freq and that will let you calculate the Miller cap.
Divide by the gain and you have the interelectrode cap.
