This weekend I’ve been working on the ‘final’ Vivat PWM – this is the ‘US spec’ one that we changed the mains transformer on. The electrolytic capacitors are stamped ‘1953’, so it’s a good early one from MkII days.

Time for some more smaller jobs!

Power Input Panel
At the rear is the power input panel. This was missing when we retrieved the vehicle from the school but the frame of it was located afterwards and returned to us.

Sponsorship for internal wiring
Now that we have reached the wiring stage, we have been looking for suitable black double-screened coax cable and connectors. Continue reading “Sponsorship for internal wiring”
TCC capacitors
We are finding that the main problem with Marconi equipment dating from the 1950s is failure of the non-electrolytic capacitors, most of which were made by TCC. Continue reading “TCC capacitors”
Sync Pulse Generator mounting
The split-unit mobile SPG (Sync Pulse Generator) that we have is unfortunately missing both its mounting frames with the anti-vibration inserts.
Miscellaneous
There are always a number of “smaller things” that need to be done to move the project forward.
Fourth Picture and Waveform Monitor
We were intending that the left-most position of the four “forward” engineering positions – the one for the “Vision Engineer” should be equipped with a BD819A precision monitor and a separate waveform monitor.
Vision Mixer
Obtaining the correct vision mixer has been a long-term endeavour, but finally one has been found. The unit seen in previous pictures was of a similar design but not the correct one.
