OT is an Output Transformer. It is the device directly between the Power Tubes and your Speakers. It takes an amplified signal and makes it huge.
A good Mercury Magnetics ( I would use the same one that Soldano uses in their Hot Rod 100 amps ) would run you between $100-$200, plus an hour or 2 of labor charges to install it.
Personally, I think it needs a cap job and new tubes and that would be it.
There should be no reason that the output transformer is blown, unless there is something that is not being said by the owner. This is the whole reason that there are fuses in amps.
The caps would definitely be dried up, or close to it and need to be replaced. This should be under $100. I don't have a set fee for this, it is strictly "Time & Materials." Usually runs about $80 for a Mesa type amp though. This would be for all Power Supply caps as well as the Bias Supply caps, and possibly the Cathode Bypass caps too.
