Any amp that old needs a full service - grounded power cord, new electrolytic capacitors, and maybe some resistors that are noisy are have went far out of spec. Every amp - no matter who makes it or how much it costs. OTs should not get hot enough to drip. I would be *extremely* suspect of an OT that got that hot. It might continue to work for a while, but I'd have major trust issues. If that was a customer amp on my bench I'd fix whatever what causing it to get that hot and probably recommend a new OT for long-term stability. The 50 dollars quoted earlier is not a reasonable price. That will cover maybe one hour of labor, depending on your location, but certainly not any parts. This uses a capacitor can, and just that part is $40 if you want an accurate replacement. There may be room in there to use smaller parts, but.........that's a different discussion. I don't see a good way to get out of this cheaply, but with drop marks in the photos of the original listing it's likely been happening for some time.
