can I use this cap? what about low inductance?

Can I use this 100V polyester caps in place of the stacked metal film specified in the leach amplifier?

here is the photo of the polyester capacitor

I do not know the Leach amplifier but . . .

If it has the same value in µF/nF/pF then yes. Otherwise I (we) need to know where it is placed to see what its job is.

Then there is the discussion about which types of capacitors are best . . . 😎

Keep the leads short for low inductance 🙂
