kevin gilmore replied to the thread The Stax Thread III.no 3rd stage current source in the 700s. reason: no current production >700v pnp transistors. first 2 stages identical to 717. 3rd and...

kevin gilmore replied to the thread The Stax Thread III.real current sources in the 727 at the top of the 3rd stage. as opposed to just resistors. real power is voltage * current * cosine(...

kevin gilmore replied to the thread The Stax Thread III.The srm717, srm727, 500S and 500T are all the same voltage power supplies, and roughly the same current in the output stage. 500t is a...

kevin gilmore replied to the thread The Stax Thread III.turns out i had the simulation for the srm727. in distortion graphs, top trace is 2nd harmonic, bottom trace is 3rd harmonic. the...

kevin gilmore replied to the thread The Stax Thread III.that is a great deal of work. i already had the t1 simulation done many moons ago. and all the spice models that go with it. for the...
