Earlier today I was making demos using my at4033 through my peavey VMP-2 preamp and Tascam 4 track and it just stopped working. I was using the preamp for the phantom power and all of a sudden the signal from the mic was cut out. The signal coming from my Audio-Technica all of a sudden just went out! SHould I send it to Audio-Technica for repairs? Does any one know the repair rates?
