OK, so I finally got the RGB amp put together. (Yeah, I guess that makes me kind of slow, but I blame Dragon Warrior 7
) Anyways, the picture is definitely brighter now, although I am seeing a strange effect. It looks like everything is smeared horizontally. This makes the picture look blurry, although the horizontal edges of things are still sharp. (i.e., no blurring/smearing vertically)
I have tried connecting each of the red, green, and blue signals individually and noticed the effect is present on all of them. This makes me think it isn't a case of me making a bad connection by accident.
I was following Moosmann's schematic when building the amp, although I made a few deviations:
1. I used transistors NTE 123AP and NTE 159. According to the cross reference I was using, I think they should be equivalent to BC 33725 and BC 557, respectively. NTE Cross Reference
2. My resistors are 2% tolerance. I was having a hard enough time tracking down all the right values in 2%, let alone 1%, so I went with 2%. I didn't think this should make too much of a difference.
3. I used non-polarized capacitors. I wasn't sure how to tell + from - on a regular capacitor, so I thought it would be safer to get a non-polarized. I had read somewhere that a non-polarized capacitor could always be used in place of a polarized capacitor, so I didn't think this would be an issue.
I went ahead and took a picture, although it didn't really capture the effect very well. First of all, I don't see those vertical lines on my TV so I'm not sure why they showed up in the picture. Secondly, the smearing effect is a lot worse looking at the TV than what the picture shows. You can still see it a little in the picture though. Anything with black on the right edge has a noticeable smearing effect in the picture (it looks worse on the TV).Yoshi Title Screen
Has anyone ever encountered this sort of problem when building an RGB amp? Any help would be greatly appreciated.
