Hey all My '66 Ampeg B-15N started blowing its main fuse last night. I'm bringing it to my tech to get it fixed up tomorrow but I can't help but imagine the worst case scenario which would be that it needs a new PT. If that is the case, what is the best replacement out there right now? As far as I know the PT is not in the audio path but will a replacement make it sound different? Is anyone out there re-winding these? Thanks!
