Aleph J illustrated build guide

^ If built to spec (I'm not sure what you're simulating), you should have 20dB gain => 10X => 5V. Your simulation is closer.

If the load is only the scope, that's a very high impedance. I am not sure what affect that may have. I'd assume you'd still get a proper output voltage, but put in your load and see.

BTW - Always use units, please. I am assuming you mean that your input was 0.5Vp and your output was 2.5Vp => 5X. If your input was 0.5Vrms, that changes things, but you're still off, just a bit further off.

Were you using a differential input? Did you short In- to GND? You typically get 0dB gain (or even slightly negative gain) without that jumper when using a SE input.

Thank you very much for the explonation. I've figured out that my signal source was producing full wave, but i considered it as a half-amplitude wave. Now the simulation results perfectly match the real ones
