Default Re: Number of tuned circuits in a set

This "benchmark" is useless. I have a Grundig 1060 "Zauberklang" (Magic Sound) that proudly proclaims to have "10 FM Kreise, 7 AM Kreise". I have to count every coil in the signal path (including LO) to come to these numbers. Ratio detector alone now has no less than three circuits. FM performance (ECC85 front end) is, as usual, crap due to only one preselector tuned circuit. I would say had it had 13 circuits limiting action in the IF would have been much better.
