Thanks for all the help and advice, foks. As I said, I haven't even seen the radio in question, and may not do for some time, but, unless I'm mistaken, the consensus of opinion is that, as long as IFT(s) designed for use with valved radios are used, peaking the cores at the correct frequency (bearing in mind the caveats mentioned by Trevor and Kalee 20 ) should be OK. Romac radios, IIRC wre made in the late 1940s/early 1950s, or at least the only one I've ever come across was. This used miniature all-glass valves. To the best of my knowledge IFTs made in those years had built-in padder caps., and adjustment was via dust cores (or ferrite cores),. I've only seen the type which is tuned by trimmer caps. in pre-war radios. However, I'm prepared to be wrong on several counts!
