..and those notes were really helpful last night as I was sorting stuff out and testing the transformers. Really good stuff.
But what I'm stuck on is whether I should use the tapped or untapped style. Looking at the schematic, I see TC seemed to use the same Millen coils in all three positions, and I'm inclined to use the three matching 3d IF transformers that check out OK per the tests on the website.
But if there was magic in using the BC453 1st IF in the first IF I would do it, I just don't see any comment about whether there is anything critical about which of the 453 transformers can be used where..and I'm not bright enough to ferret that out :)
Thanks again, that website was great, especially the BFO part (next problem to solve....)
