so i got an issue with my amp here and i was hoping for some help. when i plug my guitar into my marshal avt 150h i got a very low sound output. i cleaned all the connections with electrical cleaner and bought a new preamp tube and still get a sound with no power behind it. ive tried several differnt guitars and cables. when i move the input jack around ill get loud noises and when i have the distortion channel on it gets real loud but its not playing the sounds the guitar makes, its all just random static noise. i think it has something to do with the chip that the input jack sits on. has anyone had this problem or know where i can order that chip from?
