Thanks

--> First Rev A2 with standard transistors and 3k resistor

--> Second Rev A2 with special transistors and 2.7k resistors

The image is brighter, but sadly I can't get the effect with my camera. You can see it a little bit on the "forward" and "backward" buttons of the picture viewer.

So the 2.7k does a good job here

I will change the first A2 and add 2.7k resistors so I can compare the transistors better.

Today I found time to do some further tests.

I changed the three 3.0k resistors of first Rev A2 to 2.7k and got a nice boost of ~140mV. The image is now much brighter and looks good so far. 1024x768 is good, 1280x1024 is ok but more blurry (shielding problem).

During voltage measuring of the second Rev A2 with experimental transistors I noticed partly very high voltage (image distorts after longer use, cause the voltage rises?!), so I'm going to change the resistors from 2.7k to 3.0k.

After all I think the first A2 with 2.7k is the one that will get to Gary soon
