I looked over the listings for the radio kits on the E-place. It seems like there's three different versions of this kit.
One version has a more conventional output stage using an input and output transformer, another has an input transformer coupling some form of a complimentary pair and coupling capacitor to speaker and the third doesn't use a transformer at all! All direct coupling!
It's good fun, going back to basics!

Best regards, Dave, US radcoll1.
