Florin Stanciu Posted January 7, 2024 Share Posted January 7, 2024 Buna seara, am un amplificator Ta2400 (The.amp) la care unu din canale are un zgomot de fond foarte mare+incalzirea foarte rapida a radiatorului . Ce ii ciudat ca finali si prefinali sunt buni originali si neumblat in el , canalul asta cu probleme oarecum canta "normal" neefind in protectie. https://images.app.goo.gl/fxwR4b9q6TPDxRZF9 Am atasat link cu schema.
