Hi, I am just a little curious as to how sensitive and good of a performer this set is? I've never seen a set like this where the signal goes right from the 1st det/oscillator into the second detector with no IF amp in between. I do see where cap 17 looks like gives some kind of feedback to the tapped IF transformer so maybe that helps. No RF or IF amp has me wondering! Thanks

Ron
