Okay, so a little while ago I built my own SuperGun. It is RGB out with no encoder. The RGB lines go to 500 ohm pots and the sync goes through an LM1181 sync stripper and that's it.
I recently found out through a Twitter conversation about some other SuperGun that I am pushing too much juice into my Framemeister and that I need to bring down the signals to
the proper levels. I got my hands on a THS7374 and took a look at the datasheet, and I have some questions.
On the inputs, it looks like there are resistors all going to ground but there is no value written. What value would be appropriate?
On the outputs, I can see they are all going to 75 ohm resistors. That's fine but shouldn't I put some caps in there also? I know other systems use 220uf caps but would that work for
arcade stuff too?
As you can tell, I am in the "A danger to myself, others, and expensive equipment" phase of my modding and repair studies. Thanks for helping a nub out.
