MM-EQ; the SUPRA2024

Here are 2 files; Supra_gerber.zip (which is just that) and Supra2024 which is all KiCAD files including the Gerbers.

Here is the latest layout, and apologize for the inclusion of my ego trip, Helion Audio. The company does not exist, only in my head....
Feel free to use as is, misuse, alter, sell or whatever.

Allright, now I get sound from the SUPRA with courtesy of m0rten's PCBs. I'm using the "short" feedback setting. It's obviously in an experimental setting and I have no measurements. I subjectively feel it reproduces less and firmer bass than the OREAD. I haven't done any a/b testing, it's just from memory. Since it's a test setup the interconnects and the power supply are sub standard. As can be seen the shielding is mediocre which is noticeable when I turn up the volume. I'm very happy the have it playing after all this time. A switch to compare the two feedback setting will be added too.

The fully assembled boards look great.

There must be a clear difference in sound between OREAD and the Supra topology. Only /but the RIAA correction must not be responsible for this, only the actual core. And the cores are very different from each other.

I look forward to hearing about your experiences and your courage to experiment.

Great class.

greetings,
HBt.
