So this is a Sweep Generator based around a NE555 and two OpAmp´s. I found the schematic online and would like to get it working to understand whats going on.
Diodes: 1N4148:

OpAmp´s: LM324N:

PNP: BC557: http://www.farnell.com/datasheets/296678.pdf
The actual problem right now (its the MOSFET at the moment) is the depletion type JFET: 2N3819: https://www.onsemi.com/pub/Collateral/2N3819-D.PDF
Is there any way to simulate this in here?

I´ll probably have to do it in Spice tho.
