Hi folks,
i'm building the gyraf 1176 and meassured the lundahl transformers needed for this circuit.
nice, but the 1540 does not shot the results i expected.
we used a measuring circuit explained here (http://www.lundahl.se/pdfs/datash/1540.pdf) on the bottom right.
we used a tektronix scope for amplitude and phase.
but at the end there are some serious unlinear behaviours from 10k on and the phase is becoming less than 180°.
i have a pdf here with the results (the 5402 and the 1540) but don't know how to attach the file to this message.
maybe someone knows?
greetings
