Lost a Satruday on this Transformer!? Is there Continuity between A and B of T401 once it has been soldered in place?
Thank You,

Yes.? If you look at the circuit diagram, the primary and secondary of T401 are connected: the centre tap of the secondary is connected to the half-rail voltage derived by R401/R402.? The same voltage is used to bias the band selector switch IC to half rail.? Basically, all the terminals of T401 are connected together if you do a continuity check once it is soldered in place.
