Composite modded my Vader, still very dim picture

[davidbrit2]

I've got an NTSC Vader, and it's had a fairly dim picture since I got it. I bought a composite video mod kit from ebay (the basic kit with one transistor and three resistors), and it worked great - the picture is much cleaner now - but it's still pretty dim. Is there something I can do to adjust the brightness of the output at all? Are there perhaps some aging caps that need to be replaced?

There is a color adjust dial under the shielding on the left. I would recommend marking its current position before adjusting in case you need to return to factory. There is also a resistor mod/factory addition you can add to boost color on 4 switchers. There is a thread somewhere here in the forums.

Yeah, I used the Color Bar Generator ROM to calibrate the hue pot, and the color saturation looks okay (maybe even a little bit too saturated), but the picture overall just isn't very bright. My 7800 seems slightly brighter, though it's not a night-and-day difference.
