Back in 1964 a few years before the service launch, RBM released a training suite for dealers covering colour television, it was called “ColourVision Principles”. This consisted of a manual, audio provided on 5 LPs and a suite of 35mm slides.

I’ve been looking for this course for a number of years but only ever came across parts not the whole. Over the past few years I managed to collect the various elements, culminating in the final missing piece obtained last week, the all important 35mm slides. I now have the suite to recreate the lecture, well almost! Sadly one LP is missing there should be five, I have LP1, LP2, LP3, LP5, four is missing. Still I'm no losing hope it will eventually surface, as did everything else, though it has taken five years to get this far.

I will be documenting it all in full on the website and the ultimate plan is to film the lecture live with slides and manual inserts, for my YouTube channel, thus preserving it.

Link the Web page.

Did anyone ever attend one of these RBM lectures, or were you all too young?

I don’t remember this one but I do recall receiving a folder with lots of information around the time of the launch of colour. What colour system do the lectures cover, I can see a delay line in the chassis photo so PAL/SECAM?

I have had a set (incomplete, I think) of those slides for some while now. I was going to introduce them to my Nikon slide scanner....

We had the records and literature where I served my apprenticeship, wasn’t aware of slides. I wonder if these came later as a Mk3 chassis is pictured in them.

Some years ago I acquired a slide to USB scanner from, of all places, Aldi!

It works very well. Wonder if you could find one of those?

Pye in Australia had what I always thought was the best idea. They gave all their service techs a colour TV, in pieces, bare PCBs and all. A huge incentive to learn.

I can remember, just, when I worked for Southern Rentals at Portslade Hall, Portslade, East Sussex in the late 1960’s. Thorn would send a Technical “Bod” from their Gosport Factory, up to our workshops to give us a lecture on their latest Colour TV chassis’s. Many of us would crowd into the tea room to listen with great intent. Other than that, I would get my refresher courses from Brighton Tech, Richmond Terrace, given by Ron Bravery.

The early CTV manuals late 60’s/70’s usually ,from my memory, had excellent circuit descriptions. I went to a Len Briggs lecture on the Dual standard Pye CTV chassis, 1967/68, the lecture was excellent. After that it was study the manual and circuit descriptions. The C&G course 48 colour endorsement was obtained in 1969.

Len Briggs, while I have no idea whatsoever who he is

That is surprising, I thought everyone in the trade would have come across his writings. His "Know-How" guides are superb. I particularly found his decoder diagnostics guide an absolute godsend.

I've many of his guides, here are just a few and a picture of the man himself.

I went to the Len Briggs lecture when the G11 was launched. I was only about 17 I think doing 2nd year RTS at Tech but Len made everything easy to understand.

Although I worked at Philips and most of my training was done there, they sent us to a Len Briggs lecture when teletext first appeared. It was an excellent introduction when the 'Tifax' board first appeared. Explaining how the row address and column address worked made understanding the Philips decoder that much easier when I later attended the Philips course when they introduced their teletext board with the Philips chipset as used in the G11.

 

Philips used the Tifax board in a G8 model and a later G9.
