I found a old topic on DIYaudio about people that bought a Studer900 clone, apparently with very low ripple according to some measurements made in YouTube.
So I tried to design an LTspice model of the Studer900 to see if I could get some parameters to compare with the measured results, particularly ripple. But I didn't succeed on my plans, and it needs some additional setup corrections that I do not know which they are.
I included the original schematics, the one from the manual and the one of the clone sold by, which people are using with great praise and satisfaction. Can someone help?
The original opamp used was a TLO72, which I didn't have the model of. But the OPAx134 should work on the sim.
