Amplificatorul este construit din materiale usor accesibile oricarui pionier si scolar si conceput pentru amplificarea curentilor de joasa frecventa, generati de diferite aparate radioelectronice. Amplificatorul are o putere dirijata de 15 W cu 10% distor- sionari. in constructia lui s-a folosit schema de mai jos, cu 4-F-l tuburi electronice si anume: EABC 80, ECC81 si 2 tuburi EL 84 si EZ 81 redresoare.
Aparatul are etajele distincte si anume: preamplificator, etaj de defazare, etaj final in contratimp si un redresor. Transformatorul de retea este calculat si realizat pentru a debita urmatoarele tensiuni: 6,3 v la 2 A si 250 V. c. a la 200 mA si absoarbe de la retea cca. 75 W la 220 V curent alternativ.
