James,
The 1.5A bridge rectifiers are suspect. It is recommended to use 4A types. I have done this by the advice on this group. The 4A types run cooler due to not being run near it's current capacity. The rectifiers for the lower voltage supplies are 200V. You can use a higher voltage type if you want. If you will need bridge rectifiers for other things at a higher voltages, get ten of a higher voltage at 4A to get a price break. The price break is usually ten of an item.
It sounds like you have number of shorted tantalums by your description. Keep testing each one with one leg unsoldered. Those that are bad, leave the one leg up and note what you need to replace. With one leg left up, you know that one is bad.
You may have bad transistors. If any are 151-0367-00, check C to E. Any that show leakage, replace with KSP10BU. These have a pinout of BEC.
