An IV amp using the BS170R mosfet

[gaetan8888]

Hello

I've founded a bunch of BS170R mosfet, and I've found a IV amp schematic and mod it to use the BS170R mosfet.

It's for using it with the TDA1541A

It's not the Zen or a D1 IV amp but it sim good.

Any opinions, suggestions about it ?

I include an image of the schematic and the sim file in text form.

Thank

Bye

How did you associate the Philips sub-circuit with the NMOS symbol ?
I know this should be elementary for an experienced user of LTSpice but I don't know the answer to it.
