| To find a short between the 110 volt primary and the high voltage secondary, simply connect your meter between any point on the two (one lead to one coil at any point, and the other lead to the other coil at any point). If you find any continuity what-so-ever, then this is your problem. You must disconnect any line cord condensers that go to the chassis, however, or any leakage present within them may give you the false notion that you have leakage within the transformer. If the transformer functions normally, otherwise, you may simply treat the set as an AC-DC set, and try not to ground the chassis. Insert a .01 MFD condenser between the antenna and the radio. You can also disassemble the transformer and check for shorts in the wiring, though the trouble may actually be in the windings. If trouble is in the windings, then try not to leave the set on unattended. It is not likely to blow up, but if things are deteriorating, then it is best to be cautious. Still, if the transformer is functioning normally, otherwise, I don't see the need for replacing it yet. Transformers are expensive. If you do disassemble the transformer for a wiring examination, be careful, as the wiring may be fragile. If it is, either be ready with some heat shrink, or avoid disassemble. Heat shrink might not be such a bad idea, though, if the wiring is deteriorating. It may actually save trouble that might otherwise happen in the future (internal shorts). Thomas |
