Broadcast Engineering Museum open days 2024

[Mike Watterson]

Thanks to a valiant effort by Trevor Brown and Paul Marshall our TR70 2" quadruplex VTR was fully working and showing excellent pictures. These are very complex machines and needed frequent skilled attention when in service. Back then each fault was fixed as it happened. Trevor is one of the few engineers anywhere who fully understands these machines and was capable of tracing the dozen or more problems that had accumulated.

I'm impressed. I've seen them and wasn't allowed to touch. I get the impression they make the VCRs and VTRs I did service look like toys (though N1500 is a bit meccanno flavoured). The 1/2″ EIAJ reel to reels were very simple compared to a U-matic (and much lighter).

I can't imagine a TR70 being carried upstairs and the lift in the BBC Belfast looked ancient. Though I don't remember what model(s) they were using in mid 1970s.

The TR70 is from 1967?

I'd have liked to have seen that.

A random one from pintrest.nl circa 1968
