Does anyone know good source for lf357 in europe? Or have extra? I’ve searched all the internet, electronic component shop and secondhand ones. Some ebay sellers are not reliable. I also found lf357h and mba357 yet again, i don’t know if they are original or not.

The power supply to the circuit is low. It can not provide confident transistor closure control.

You can make a ship of iron. You can also make a ship of wood. Both ships swim ...

Thats hard to understand but does that mean yes fets will work,

Sasho, for experimental purposes, can you replace the 4066 switch with J113 fets , would it work ? thanks.

The total conductor is "+" . Measurements are made to it.

Thanks

It appears I had a new fake or faulty TL062, I now have these voltages
pin3 plus 7.82v
between pins 8-4, 8.8v
between pins 1-8, 4.3v
between pins 1-4, 4.5v

At this point in time I am not convinced the power supply virtual earth system works properly,
I have built it but very uneven + and - voltages from 062 opamp

anybody good at spice ?

[Andi68]

There is nothing new for me yet

[ivconic]

No progress yet!?
No videos?

I live in Germany.
I already get the LF357, it just takes time.
