Heater and Cathode tied together, that's easy, heater must be DC, and you have to
be aware of what heater wire gets ground, and which gets the 3v. You will also have
to come up with focus circuit biasing and build a blanking circuit. Your clock board may have
an overkill on output wires.... Maybe there is a ground point for every axis? or a + -
for every axis, you have the schematic or pinout on this clock?


If the clock has adjustment pots, then probably for centering, and amplification for
each line. Remember scope tubes have 2 v plates, one up and one down, 2 h plates,
several focusing elements, and the usual heaters, g1, g2, etc.
