As per title and was the CRT delta or in line kind regards Bob

Can you provide any screenshots or links to online clips? We have a LOT of monitors at the Broadcast Engineering Museum and may be able to identify them.

I found this video. https://www.reddit.com/r/BritishTV/comme...ideo_show/ The Quadruplex VTR is, I think, an Ampex AVR2. Though it rather looks like a mock up prop. As for the monitors it's hard to tell as only the screens are visible. Possibly Barco CTVM3/51 which were common at the time. Delta gun. https://collection.sciencemuseumgroup.or...ur-monitor Unlikely to have been Prowest PM22/7 as getting that many to work at the same time would have been verging on miraculous.

This photo: https://muuta.net/KennyEverett/Thames/tBest2.html with a giant 2" tape spool is great.

Hi Jeffrey thanks for reply & info would like to see the wiring that goes to the monitors from the video mixing desk.The Kenny Everett show is on free view CH 71 Thats TV 3 at 11.45pm will keep an eye out for the giant 2" tape spool episode kind regards Bob

If all the monitors are showing the same picture, the video signal is simply looped from one to the next until it is terminated with 75 ohms at the final one. The co-ax used would have been PSF1/3 which was ubiquitous in the world of analogue broadcast: https://www.fscables.com/sites/admin/plu...90PS13.pdf This BBC spec cable was made by several companies. It's now obsolete.

If the pictures were degraded by looping though too many monitors then they would have used video distribution amplifiers such as: https://www.bbceng.info/ti/eqpt/AM4_520(1).pdf

Hi in some programs the monitors show different live pictures and some 3 monitors are not displaying any pictures (fault ?) . Bet that cable from FS cables were not cheap is the distribution rack mounted as some come up for sale kind regards Bob

Many thousands of yards of PSF1/3 cable would have been used in any broadcast TV installation. I don't know how much it cost back then. It won't have been cheap but I don't think it was terribly expensive. Back then, all broadcast kit was pretty expensive. Canford https://www.canford.co.uk/ was (and still is) one of the major suppliers of cable, connectors etc to the BBC. I think they acted as a sort of extension to the BBC's own Equipment Department. Mark Hennessey may be able to confirm this.

At the Broadcast Engineering Museum we mainly use the newer and thinner Image 360 cable: https://www.argosycable.com/product/imag...1hHysmyhXK though we still use plenty of PSF1/3. We also have quite a few AM4/517 etc VDAs in our stores. Up to eight of them fit in a 3U rack. We don't use them very much. Nor their BBC-designed successors. This is partly because we mainly use SDI (serial digital interface) for our main infrastructure. https://en.wikipedia.org/wiki/Serial_digital_interface For us, this is the original standard definition 270Mb/s standard. All analogue sources are converted to SDI, audio is embedded in the SDI signals as needed. SDI is converted back to analogue RGB or PAL to feed monitors etc. Where we need analogue VDAs we mainly use ones by BAL (which I designed many years ago!) or Avitel. The latter suffer from intermittent connector faults.

Bob, you really must visit us one day. Our next open day is planned to be Sunday April 5th 2026. Then the first Sunday of every month until August and a Heritage Open Day weekend in September.
