oh a little history, all the bias/hv/drive waveforms check out, sweep tube is good, just a bit short on sweep. I could increase it by adj the horz tube bias 9there is a pot for it on this one) but that would shoot the HV up too high. when HV was adj to 25kv (brightness all down for min beam current) I would get the correct HOT current but just not enough sweep. I even went so far as to buy a new yoke, but never got around to installing it. The cap thing was just an experement based on looking at other schematics that had a provision for increasing the sweep, which involved a cap from the red lead of the horz sweep to ground. There was no such cap in this set or provision for it but I did see the 68pf internal cap across the horz sweep leads.
