If you have not done so already, REPLACE THE POWER SUPPLY FILTER CONDENSERS !!! before you do anything else, before you turn it on again. They are the most likely to go, and if they do they can take the power transformer with them. Actually, I strongly suggest also replacing all the paper condensers, and checking all the resistors for out of spec ones and replace those too. Once done you will have a radio-phono which will be far more reliable, and probably only need a tube replaced now and then for the next half century.
