Šteta što izl. buffer nije realizovan kao LP filter jer bi se tako dobio bolji THD: drugi harmonik na -110, a treći na skoro -120dBc Sad

Pridružujem se pohvalama za uradak!

Da, izlazni buffer mogao bi biti LPF!
Još kad bi zaposlio dodatan buffer pa da on ganja sijalice u NFBju i rastereti tako opamp Wien-ovog mostiča,
koji bi imao tako manjim pterečenjem odmah bolji THD!
