Hi Andy,
The Cossor takes its 4 volt heater supply from the timebase heaters.
One advantage the Cossor 65K has over the Cathodevisor tube is that it has an indirectly heated cathode so there is no requirement for an isolated from earth heater supply. If all fails with the present tube I'll have work out how to fit John's CRT in the set. A new adaptor plate perhaps?

DFWB.
