Hello,

does anyone uses FEU-35 ?
How well does it perform?

What schematic did you use for voltage divider ?
Any capacitors with the voltage divider ?

best regards
Paulo

Older analog of feu85, quality is a lottery because of long time passed since its production. Can be used for experiments.

In these pdf, the resistors are 100K, if I use 10M resistors I was thinking to adjust the capacitor value in the same proportion, 100 times smaller, what you guys think of this ?
