For future reference, the best way to bring up a piece of gear that has been sitting is with a variac which is a variable power supply. I turn on the component and give it a couple of hours at one volt input, then a couple of hours at two volts, then five volts, ten, fiffteen, etc. until you are up to 115 volts. There are two reasons for this, first the dielectric charge on the caps can reform properly, generally eliminating 60HZ hum and cap related problems, and second, if at any point you smell burning smells or any part is abnormally hot you can back the voltage back down and do diagnostics with less damage downstream.
As to your problem, salvage transformers can be had rather cheaply however there are a dizzying array of different secondary taps. And that does not yet address what made the
transformer smoke in the first place. One suggestion, substitute new output tubes if they are available or test your existing set. If you have the same problem junk it for parts.
