No, it's just got a few thousand gigs on it and the techs around here try to fix whatever the problem is without sacrificing as much of the original amp as possible. So that means the insides are a patchwork of small fixes by at least four techs that I've used and who knows how many before.if I had someone "blueprint" the amp and replace everything it would end up being a completely different sounding amp anyway.Seems odd that you have to repair the old Fender so often. Is your tech perhaps missing something?
