Hi Fran , Tom's method will work for you , I've done this many times and in fact I did the very same thing recently to a Temple brand TRF radio and it worked great . A couple of fine tuning tweaks here may be to use smaller capacitors for the coupling , I've usually found that much over .001 caused distortion , and with the Temple there was a bit of a buzz in the sound till I fed the plate resistor(the 10K resistor) with a small RF choke . The radio I did had only one bad interstage transformer and was an A/C powered unit , if you run your's from batteries you may not need the RF choke .
PS , there are no stupid questions here , we are mostly old men (
Tom being the exception) who have spent a lifetime learning this stuff , and we are here specifically to help people learn what we spent all those years learning . Oh , and I love the "I is for him , E is for her" , my middle name is Francis and many people don't know the I or E spelling for male or female
