Marconi Mark iv

[austvarchive]

I have an almost complete chain here - ex ABC, and possible ex BBC as some of the boards had BBC markings on them. It has the large PSU unit and CCU cases and remote control panel, however is missing the main master panel

There was another one around ex HSV7 that was supposed to be complete and once working that another collector had, however it really wasnt looked after and had a lot of damage/abuse to it in this persons care which was a shame.

Another HSV7 camera was donated to the television museum at mornington many years ago and it was claimed to be working at the time, last i saw it was on display at the ACMI exhibit in 2006 or so, with added scratches and handling damage and I was told all the external stuff like ccu/psu of all the gear was never retained on items, so its just a prop now.

This is one of the most distressing aspects of a "proper Museum" run, no doubt by Art types! would they keep a vintage car and take the engine out because in made it lighter! GRRRRR.

I hear many stories of the decimation/loss/miss-placing of someones donated collection. The last one I heard was referring to telegraph equipment. I am far from convinced that a Museum that has to justify its existence in terms of bodies through the door and or profit is a safe place for anything.

All of Marconi's camera Mks went through a process of continuous improvement, so they were sometimes referred to as an "A" or "B" type. For instance the MkVIII had an official B suffix from about serial number 400, but even this depended on what type of tubes the camera could accommodate. (HOP Tubes).

All of the cameras had /00 or /01 on the end of the BD683 B3096 number and so on for line standard & mains voltage/Frequency differences.

Time permitting I will return the the MkIV on my site and redo the pages, Have a lot of stuff to but it may take a while.
