I just noticed a strange thing, the bypass diodes(D5,D6,D7) that are across the ldos are rated at 10V. If you use 24V power supplies D6 and D7 are ok with 8v across them but not D5 which has 16.7V(24-4(voltage drop across R21)-3.3) on it.
So with the standard 24V supplies D5 needs to be replaced, I use 28V power supplies so I need to replace all of them.
The actual ones are rated at 3A. As you increase the forward current the leakage current increases too so what is a minimum value that can be used for the forward current to protect the ldos?

All these years that I waited to build this I hoped that maybe if I wait enough the panels will draw themselves as I want them to be but unfortunately for me that didn’t happen. In the end it wasn’t so difficult as it seemed years ago.

Not going for dual encoders? Would make the panel simpler and the buttons obsolete. Just an idea.
It will look better indeed but removing the buttons will remove some of the shortcuts the input buttons provide that I use and find convenient.
I will try to draw it to see how it looks.

Nothing 🙂 make only the faceplate more complicated.
I will go with both dual encoders because of the symmetry and also with buttons because of the direct input select and shortcuts.
gionag did both and the panel is looking very nice.

I have started with the idea to have both encoders and no push buttons but after I started to use the preamp I decided that I will go with only one encoder and the push buttons.
@Alex_twn there is one thing that I noticed and I am not sure if it’s ok or not. If I change the input type on the fly from the front panel and after I restart the preamp, after the restart the input goes to the same state it is saved in the settings and not what was previously selected from the front input buttons. Is this behavior normal?
