Just a follow up...I took some readings on the rectifier socket mostly to see if the transformer is working properly. I'm getting the proper voltage on the rectifier plates but not the rectifier filament pins. I'm getting little over 1 volt and the print wants 5v. I was looking at the blue wire that feeds the +C59A and as I moved the wired the volts jump to 5v then drops and repeats. At one point, I heard crackling coming from the speaker which I haven't heard any sound from the radio yet. I'm thinking short inside the transformer. I would like to just replace this transformer but I haven't seen any available for sale. Im also thinking to just open up the transformer and see if these wires can be replaced. I'm not sure if this solves my original issue of C59 exploding though but was happy to hear sound from the speaker.
