Hi Terry
I think you are right, although there are minor signs of the slugs being twiddled, that may have been from initial setting up at the factory.
There must be a fault somewhere, my first try after making a 85 turn coil "dummy aerial", as mentioned in the alignment instructions, proved absolutely nothing passing through the IF strip.
So I gave up with the coil and connected the signal generator to the base of T305 via a .01uf cap. Nothing.
I then started probing around with the signal generator and the only place I get any sort of tone is on the end of the detector diode connected to C336 & R327, and that is very faint, but the D303 tests OK on a diode test (whilst still in circuit).
Anyway given up for tonight as my back is aching.
I will have another look tomorrow.
Mike
