Hi, I need help from you veterans. I am pulling my hair out! Stumped right now on a Crosley 56TV-0. I have replaced all the tubes, caps, speakers. Done everything I can think of. The radio plays, but the sound is kind of garbled, and there is a buzzing. I can not get the sound clear. Maybe this will be an easy solution for one of you. I am so frustrated right now! Any suggestions would be greatly appreciated! Thanks very much!!
