it's now in gif format, perhaps you can check it now. ^_^Hello,
Please post the schematic as an .PNG or PDF file.
Not every one (like me) can read the .sch file.

Without parameters for the JFET I see no way to calculate its gain. Are you sure they were not given? Was a specific JFET such as an MPF102 given so we can look up the manufacturer's data sheet? Or is this a lab project where you can experimentally determine the parameters?it's now in gif format, perhaps you can check it now. ^_^
I'm sorry there was an error on the problem that I've posted, I wasn't able to copy the given correctly Idss = 10mA Vp = -4VWithout parameters for the JFET I see no way to calculate its gain.

Thank you so much for resolving this problem!Here's my solution for the gain of the first amp. I didn't show all my work, but there's enough for you to see the method.
The gain of the second amp will be the resistance seen by the collector divided by the resistance at the emitter. And then 4:1 step down to the load. Be sure to reflect the resistance of the load into the primary of the transformer when you calculate the gain at the collecter.
Actually, that was the solution for the first stage only. But you're most welcome. The second stage is kind of complicated so I solved that, too. If you were also given the inductance of the primary of the transformer or its impedance, then that has to be included. Without it I assumed it was large enough to ignore.Thank you so much for resolving this problem!
