Hi Tim,
         I guess you didn't bother to do some basic calcs using your
resistor values then:

The first point to be made is that the higher the power dissipated in
the bleeders, the less there is for your coil. The second is that
with four in series = 2k, 60mA x 2k = 120V (which is the RMS voltage
your transformer could deliver with the resistors planted across it).

      A bleed resistance of several megohms capable of withstanding at
least 11kV would be a better idea.
