On the input transformer the primary is 1.2kohm and secondary 4.8kohm in series. in parallel it is 300 prim. and 1.2kohm sec. for the preamp I need the series configuration. On the output transformer the series primary is 200ohms and series secondary is 600ohms. the parrallel prim. is 50ohms and parallel sec. is 150ohms. Which again on the output I need the series configuration aswell.
After looking at your products. and im trying to do this on the cheapest budget and mount everything on pcb, for my input tranny would it be possible to use two of your PC600/10K together wiring the primaries in series and the secondaries in parallel to get 1.2kohm primary and 5kohm secondary.
Also for the output transformer would it be possible to use one PC600/150 backwards and adding a 50 ohm resistor in series with the 150 ohm secondary to get 200 ohms. Then I could acheive my 200 ohm primary and 600 ohm secondary.
You cannot wire two transformers in parallel. They would have to have the same core. Resistance is not the same as impedance. A resistor is a DC resistance as impedance is AC resistance. You should be able to us the 150 Ohms for a 200 Ohms the turns ratio should be close enough.
