Things tend to only been replaced when they’ve literally broken beyond repair or there’s a pot of money for a trial and a region benefits from it. There’s very much an “if it ain’t broke” mentality and the regions do very well keeping ancient kit going. Before ViLoR most local radio stations were using Mark III desks, a classic BBC in-house designed mixing desk. As I understand it, they were all constructed and deployed centrally starting in the late 70s-80s as local radio stations came on stream. (There was a Mark IV but only a few sites got them). These wonderful desks soldiered on right up until the end. However the engineers keeping them going had to form a very vibrant group within the BBC trading spares, parts and components. A few stations were left with only one operational desk by the very end.
TV isn’t quite the same but there’s still a make do and mend philosophy when it comes to things like Astons. When the thirty year old one I use broke recently (the power supply failed - which isn’t really surprising after thirty years 24/7 use) we scouted around and found a couple being thrown out from BBC Cardiff. Replaced power supply, threw the switch and it’s back in daily use again.
It’s a rash generalisation but kit built in that era is
resilient and easy to fix if you can find the spares.
Kit purchased in the 2000s, tends instead to be PC based and is much more dependent on the quality of the PC it’s based on, the operating system and whether it’s updateable and supported.
Sounds like there needs to be an internal craigslist for BBC employees looking for parts.
Don’t let anyone treat you like you’re a VO/SOT when you’re a PKG.
