Hi Bud and all, The biggest objection I have seen to the use of a "zapper" is charred birdseyes. The zappers that I have seen are as you have stated filament transformers and in my opinion are much too large for the job. My zapper uses a 12 volt transformer from Radio Shack rated at 2 amps. This is enough to heat the center pin and free it up. Obviously this would damage the transformer if it was held on too long but you do not need to do that. A second or two is all that is needed.
