Yes, I was suggesting that the capacitors could be removed and the power supply to the coil should still work, assuming the schematic to which I linked is reasonably accurate. Rather than burning more traces, though, I added that putting a light in series might keep it running long enough, since current will be limited to the maximum current of the bulb, to find the faulty component. One consideration is even if the faulty component is found, you may not be able to find a replacement.
Can you try a known good heater coil with this unit or conversely, the coil you have been trying with a known good supply?
The more details you give, the more I think that the problem is not where the failure occurred. That failure point was just the weakest link. When you get down stream, you are dealing with high frequency and high voltage without a schematic. Any problem there may be a bit tougher to solve.
