I cannot thank you guys enough for your friendly advice. I am by no means a novice, but new to refurbishing radios, and thoroughly enjoying it. The audio is a breeze, and technically I should be well up on inductors and Amplitude modulation, but my career careered away from what I enjoyed most, and now I am retired and have time to learn and re learn, I appreciate even more, professional hints and tips from such as yourselves - this gives me keys which I can use to jump steps - a bit like the keys in maths which only a few teachers can hand to you, and once you have them, it's plain sailing. I did baulk a little at the mention of 'big' henrys, but what you say makes sense, and as yet, I have no inductor - I am about to order a few 20uH chokes, and look forward, Sheldon fashion, in true Geek spirit, to have 'fun with chokes' and brush up my electronics maths again.
Thank you,
Dave.
