Can you identify

At the beginning there's a TV-screen sized demonstration oscilloscope... we had one at Leeds, can't remember the make, it wasn't one of the usual scope firms. Later there's a Cossor 339.

The large screen Oscilloscope might be an Airmec.

We had a large screen Airmec oscilloscope at college when I did my City & Guilds day release course but I can't remember if it was the same as the one in the video.

EDIT: Yup, I was right, an Airmec 279 is shown in this link:

Yep, Airmec.

Blue trace. Low bandwidth.

Also views of the Leevers Rich 8 track tape machine supplied to the Radiophonic Workshop in the early sixties - probably the first 8 track tape machine in Europe.

Fascinating film, a tragic genius.

I watched that video on YouTube yesterday and I've only just seen this thread this very minute, and because it was also mentioned in another thread regarding a computer problem, which I've only read a short while ago. That video kept popping up at me while I was looking and viewing other music related things and had been doing so for a couple of days until I finally clicked on it to view it. YouTube must know something about me and what I'm likely to want to view...probably even knew it was mentioned here and that I'd likely be interested.

It's nice to know that Ron Grainer credited her with her most famous work even if the BBC did not.

I also spy some lovely Philips machines (cant place the model). What I wouldnt give to spend just one day in that fantastic place.

A while ago I made some very "radiophonic workshop" like recordings using some glass jars and a Ferrograph Series 5 + Pioneer RT1011L as a "multitrack".

Happy to link it here if anyone's interested.

Search online for “ BBC Engineering Monograph No51 - Radiophonics in the BBC”
for some more good info and pictures. I have a jealously-guarded original copy.
In the late seventies I actually joined the BBC with the sole intention of working in the Radiophonic Workshop; it didn’t happen. I was promptly pushed into television engineering and the excitement of PAL video. I did visit Maida Vale on a number of occasions and eventually managed to wangle a short informal attachment to engineering there. By that stage ( early-mid 80s I would guess) there was little of the classic gear left.
The other Engineering Monographs are also definitely worth a read, covering a very wide range of topics from when BBC engineering was a force with which to be reckoned
Cheers
Pete

These are EL3566s, otherwise known as the Pro20 - EL3503 deck and EL3740 amplifier. Excellent machines, and a delight to edit on - only the Studer A80RC was faster, in my expereince. I built a stereo Pro 20 out of two surplus BBC machines in the early 80s, using Branch and Appleby heads. Worked a treat - and then I was idiot enough to sell it!

I would love to hear, again,

I love tape and noise, I can hear noise which is true on tape, nevermind,

I got this thing messed upin my brain called 'perfect pitch' which can be annoying and it is all of the time !

A so called tuned piano sounds horrible to me.

Sorry fellas and Ladys for moaning, I dunno what frequency my mind is,
but I do love live concerts, music, speach, stuff, un-tampered noise and a good ou'l rack from nature
