<p>Theta je prototipno pojačalo napravljeno u dva potpuno funkcionalna primjerka. Bora je u svom zadnjem periodu za to pojačalo izradio i cijeli support sklop DC zaštite, paljenja, temperaturne zaštite, display itd. bazirano na njegovom OMNI protektoru.
Pojačalo se bazira na <em>Hawksford Feedforward Error Correction</em> topologiji koju je u svoje  pojačalo 1984 godine prvi implementirao Bob Cordell. Theta se od pojačala ovog tipa razlikuje po tome što u izlaznom stupnju koristi bipolarne tranzistore umjesto uobičajeno upotrijebljenih mosfet tranzistora.
Drugi funkcionalni primjerak (ustvari prvi napravljeni) je kod mene, a u konačnoj varijanti predstavljen je na Triode festivalu u Šibeniku 2013. godine. Pojačalo je u stalnoj upotrebi sve do danas.</p>
