First mono hybrid to use an IC

Hi folks,
What was the first production black & white hybrid TV to use an integrated circuit??
A set I have at the moment got me pondering the question!

I have an Ecko fitted with the 169 chassis; it was manufactured around 1974/5 and uses two IC's, a TBA550Q and a TBA480Q. The earlier version of this chassis uses a TAA570 and a TAA700.

The next logical question is - what was the first set to use two IC's?
And, did the manufacturers use the inclusions of an IC or two as a selling point?
Cheers,
John

They certainly did on my 1969 Bush CTV187CS which had a single IC on the decoder, so much so they felt it worthy of printing so on the control panel ( see below)

No idea on your other queries regarding mono, will be interesting to follow.

Hi Chris,
The later A823 had a two IC decoder didn't it? I didn't think the A823 went back to 1969, I remember fixing a fair few of those when I got into colour, they must have been ancient old bangers by then!
Actually it would be interesting to figure out what colour set first used an IC as well.
How about a 'notable milestones' feature for the website?

I already have a page which is crying out for expansion https://www.radios-tv.co.uk/?q=node/146 so this and any other ideas would be welcome additions.

Didn't the Decca MS2400 single std hybrid B&W series from circ 1970 have an IC as well as valves and transistors? I remember the 24" MS2420 I think it was. The PCB was tiny, looking rather lost in the large cabinet. Can't remember the IC type nor its function, been some 30 years since I've last seen one.

Cheers,
Brian

NICAM stereo TV's first broadcast in July 1986 and the first all-transistor TV (BRC 3000 chassis, 1967) are notable additions, although not really in line with the milestones in that page, which seems to be milestones people would really notice.

Oh, and the first Trinitron TV to arrive here, in 1969/1970.

Hi Aidan,

Actually it was the 1967 BRC 2000 :thumb see here https://www.radios-tv.co.uk/pivotx/?p=19 ... model-2700

I don't think I've seen that before, I wonder what else I've missed ?!

In my head I have the idea of a scrolling bar kind of thing with pop-up / clickable images at the relevant dates. If the scrolling bar was across the middle of the page you could have the sets on the top, linking to the collection and technical achievements underneath linking to an article.

...... Decca MS2400 ......

Cheers,

I had totally forgotten about the Decca sets!
Was the MS2400 the one with a single PCB living horizontally on the bottom of the cabinet, or am I thinking about something entirely different??

The early model Pye single standard Mono used one ic in the sound stage and had a subpanel in the If area which was to replace an ic which was fitted to later versions, I think the mother board was also etched and drilled for the ic alternative when it became available.
ISTR that early G8 520s had a similar thing on the RGB board.
That would suggest that these early models were produced before the ic's were in full production so maybe the first? I can't remember the chassis number of the Pye mono set but it was the same layout as the 169 with a mechanical tuner. Did Pye go from the 368 to the 169 or was there a model in between?
The mc1330 series as used in the Decca gypsy, ITT "Featherlight" (ooh err), Thorn 8500 etc was a little later , around 1971 possibly?
Blank raster and foreign radio stations when they died because the tube flashed over or someone dropped a hat...

Graham,
That's a great looking set, I don't think I've ever seen one before.
What's the paper-clip all about in the second picture??

That B&O looks nice. Never seen this one before. The Decca mono set, MS1700,MS2001,MS2401,MS2020, MS2420 used the Motorola MC1351 IC in the intercarrier sound stage. I also have a feeling that GEC in their series 1 single standard hybrid set also used an IC in the intercarrier sound stage.
