What’s with the 100 ohm resistors in the feedback loops, btw?
The TL084 inputs have very high resistance, so adding a small resistor in series doesn’t make much sense: 10¹² + 100 = 10¹²
(also, TL074 and TL084 are the same thing, as discussed e.g. here (when they’re not, the more common TL074 is better) so no need to source one if you already have the other)
