Hope some of you that have more experience with the Ampeg V-4b can be some help. I have posted on here before that I have a V-4b that had Coke spilled on it while I was playing it and it blew. I have since replace all the tubes but now it still will not power on. Is there a step I can do before ordering the the powering transformer and/or output transformer from fliptops.com? I have a feeling these are blown as well.
