I need some fresh ideas here as the video input amp is really kicking my backside. The top trace is the output of my Tricaster with a chirp pattern going into the video amp, the lower trace is what I'm finding on the grid of the 6MU8 which has been disconnected from the set video detector and has a 470k resistor to ground. On the amp board the heaters and +285V are bypassed to ground via 0.01uf ceramics but it seems like something is ringing. Here are the images of the scope, these are about the best I can capture.
Thanks in advance for any insight, I'm close but missing something I'm not completely sure of.
