Thank you Tony, that's nice to hear, I'll start building the prototype tomorrow then :)
PS: forgot to add the BD139 base resistor for protecting the op amp when there's nothing attached to the 2n3055 collector.

Hi again.
I need a bit of help.
"In the Linear Mode the Input Common-Mode Voltage Range Includes Ground and the Output voltage Can Also Swing to Ground, even though...
Thank you for your reply.
What simulation program are you using? I've had no idea that slew rate affects it that much. I've just checked the datasheet, I see now that it's a bad choice (assuming that I'm looking at the right thing :D).
The R part of the transformer primary's impedance is 82...
Different oscillator frequency? How come?
The shop didn't have TL062, and no one sells signal transformers. I could order these for china, and I probably will eventually, but it'll take a lot of time to arrive, so I tried to do with what's available.
The output signal is somewhat useful...
I was hoping it wouldn't come to it, finding a gapless core is not an easy task. I thought I got away easily.
Unfortunately, I don't have an access to an oscilloscope.
Could you tell me why do you think that transformer is the problem?
I know it's not linear, but his meter does not saturate...
Hello!
This is my first post here, and I hope I won't break any rules :smile:.
Anyway, I was trying to build an ESR meter from this LINK, and I was hoping that someone could help me and guide me on how to solve the problems I've encountered.
My current setup:
I didn't have the same...
