I checked those (in place) without seeing anything alarming.
Maybe I will break down and install the replacement quadrature transformer. But first, I want to mess around with the breadboard circuit a little more, to see how close I can get to the ideal frequency. If there's any component tweaking to be done, I'd rather do it on the breadboard.
