Hey chip
Another question. When you say you have HV to the tube, is it the cap of the 1B3 when disconnected? Do you still have an arc with it connected as good as when disconnected? The doorknob cap (under the 1B3) could be leaky if the set loses it's HV on the cap of the 1B3 when this bad. I've never seen one open but have conneted sets without them and the set still played OK.
Also, does the 5U4 get red when drive is turned up with the 1B3 cap disconnected?
I have to dig a schematic out this weekend to work on the RAM fly connections.
