Hi guys

I hope someone can help me out with this one. I want to try a simple PP amp, with balanced input transformators. The circuit with the complementary MosFet's works with a simple green lighting diode as only purpose is to bias the MosFets. I want to use 1/1 (600/600 ohm) impedance transformators between my NAD M51 and the PP amplifier. The NAD M51 has a balanced output with a gain of +10 db.

It seems, i can't solve the isue of implementing the right trafo data or is there another problem ?

I've added a TSC file named test2.zip ( for use in TinaTI ) and a picture of the circuit.

I'd like to know a simple answer for Spice 3f4 models myself ;)

Okay geek

I don't know why TI has made these simulations for transformators as DCR of coil and number of windings :confused: ...instead of making it as simple as primary/secondary ratio and impedance.

About my isue of the amplifier, it would have been easier if it was this SIT transistor amplifier project, but it's not !

And as you know, # of windings is useless without the core Bh and Al parameters, as well as dimensions :censored:
