Recently picked up this super clean 68 B15N for only $200 because it blows fuses and hasn't worked for an unknown amount of time. So far everything internally seems fine. It seems to have been serviced in the last 10 years based on dates on some components. Someone before me very obviously maintained this amp just going by the internal condition. I think the power transformer may be bad. Is that a common failure that I can fully prove before ordering a replacement? There are 0 amp repair places near my location so DIY is the only option.
