Hi Kirk!
Those lab rats have a way of infecting us with uncontrollable desire to bring them back to life.
My 4 is doing very well, but the chroma needs a good alignment. Can't get a decent NTSC bar pattern, and the blues take over the greens at times. Gated patern looks semi-OK. Couldn't ask for much better Y channel response though, nice and sharp. I love the darn thing!!
Been busy with the theatre organ group lately.
I'll be in touch.
Kevin
