Trying to bring some life back to this radio.
First off, this was my journeymans radio until today when it fried. We had wired up a few temporary receptacles for tools and tunes. Well, apparently we "lost the neutral" this afternoon. Since the recep was a leg off of a 480 3ph supply, when the neurtal came disconnected, the once 115v circuit was now supplying 187v. It fried it. He said i could take it and try and fix it so i did.
I cant find a schematic and visually nothing looks burnt or exploded. When i tested the AC pwr in jack i got 120v. It then goes to a transformer where its stepped down and rectified to a voltage i can only assume is 7.5v (I assume this because it also be powered with 5 D batteries which the radio says is 7.5v.)
On the other side of the transformer i get no reading ac or dc.
I have 3 questions
1. Am i right in coming to the conclusion that the transformer is burned up?
2. Assuming 7.5v is the output could i get any transformer within the specs to replace it?
3. Is there any way to find out exactly how many amps the radio pulls on the dc end?
The power specs are AC 120v 60hz 11W but i dont know if thats true after the transformer
