  • Ah yes, shunt regulation of the HV. Very wasteful way of regulating, but only way back then. HV regulation was so important to color tv. Thanks for posting.

  • Translation (via Google):

    PD510 ballast tube in operation.

    CRT color TV Nordmende Spectra Color Studio S, Built in 1967.

    The darker the image is, the more power does the ballast tube, its anode glows accordingly.

    Operating values: V = 25kV, P = ca. 35W

    .
