[Elecraft] 2.25:1 balun

[Vicens Llario]

Hi to all the crew

I am on the way of refurbishing my Lightning Bolt 2 element delta loop
and I am looking either for a spare transformer to feed it or
alternatively for a schematic diagram to homebrew the transformer. If
anybody owns one of those transformers and would be willing to part with
it, please let me know. Any comments or suggestions on how to build this
2.25:1 transformer will be welcome.
Thanks in advance and best 72
