The EHT transformer has been refitted. The anode of the CRT is now receiving the full 4KV, sufficient for the Emiscope 3/4 CRT to display a very bright picture. The ion burn doesn't appear to be so noticeable. But this is not the end of the restoration of this set. The two diode interlace filter will be reintroduced into the circuit. Instead of the separate interlace module made by the engineer who modified the set all those years ago I will use the existing D63/6H6 interlace diode. The original EMI circuit uses one section of this valve.
A replacement loudspeaker will have to be found to replace the badly damaged original. Finally the cabinet will need some attention. Hopefully the worms have vacated the cabinet.
