That does look so much better. Looks like I'll have to acquire another case for the mongrel board when it's ready then.
If it ain't broke, test it to Destruction.

So back to the plot...

My newly fixed up STFM motherboard, and I have just fitted the previous SEC booster to make sure things are stable before I start plugging in the next board...

Getting better :)

Likely will remove the pots and used fixed resistors on the next version.

I've been experimenting with resistor values. Works out at like 9.5K, 400R.... or as in now, 33R 55R. Odd how the ratio changes :shrug:

In anycase, the lower resistor values seem to give a cleaner "white" colour, so I am going to stick with those. I tried 68R and while the colours are brighter, it seems to cause some odd ghosting & likely saturation. So its as bright as it can be with that resistor combo. Might not be to everyone's liking, but can't do anything else anyway.

And theres always the brightness adjustment on the monitor which is what I used when coming up with the values I sent you.

Yeah, I've got mine at 100% and its fine, but I still think it should be brighter, but could just be my crappy monitor.

V3 PCB. Pots gone, resistors added. Also had to fix the audio connector holes (tiny bit to small :roll: )
