I don't have any of this specific transformer, but I DO have a TY-141P which has the same impedance on both sides, just a wider frequency range than the 42TL218... we shall see...
Just built this and found there are 2 small mistakes in the layout (as compared to the schematic) 1/ the 4K7/100pF (left of IC2/across Gain Pot) 2/ Q2 needs to be on the right side of the cut (at 17F) Had these followed the schematic and it works.
