Am cumpărat un astfel de aparat cu mici defecte: CV blocat mecanic, ax gripat revenit după lubrifiere, Potențiometru de volum - întrerupător defect(piesa mică albă ruptă în două, nu ține lipit cu picătura doar la 2-3 acționări). Am modificat blocul UUS pentru a intra bandă 88-108 MHz(nu toată) prin scoaterea a câte o spiră de pe bobinele L3 și L6.
