On Tuesday night ABC has a series "Back in time for dinner".
The first one, 1950s, aired last Tuesday. You can see it on IView.
Next Tuesday is the 60s. You'll see an HMV "Windsor" PU series chassis there, It was purchased by the produce not running and was that way when the episode was shot. (They may have edited in some later shots, I don't know)
It was brought to me to be to get it running for the 70s episode where the changeover to colour (my Kriesler TV) happens. With content shot off the screens I'm told.
I haven't had a preview of this series but if the 50's episode is anything to go by they should be excellent.
Pete your National appears in the 80s episode.

Watched the show, just as I remember it, for the food and surrounds.

Seeing we bought our current house in the 1960's and have hardly changed a thing, same kitchen, same 60's car in garage!, every thing we saw in the show just looked normal. Well we do have a colour TV and we did buy a freezer and a fridge back in about year 2000. We are not fast adopters! Ok, Barbara did get a new washer to replace the wringer/washer we started with, the wringer was powered, I was not that cruel!!

I was disappointed there were not any TV's on the 50's episode.
I guess their logic was that not many average families could afford them.

Saw a preview for the 60's episode. It shows a HMV "Warwick"
Was this similar to the Windsor?

Can't wait to see the transition from B&W to colour

Producer wanted a working 50s TV but didn't find us in time for the shoot.

Yeah HMV is a "Warwick", I think the Windsor was the console version. My mistake.

"Can't wait to see the transition from B&W to colour"

A good opportunity perhaps to show a bit of Aunty Jack and the coming of colour, seeing as this was an ABC show. Aired at a few minutes to midnight on the 28th of February 1975, beating the commercials by a few minutes.

TV in the 1950's?
We had to go down to the big TV shop at Burwood (lived at Flemington, that's Sydney suburbs) and stare through the shop window where they had a set for the poor people to look at.so they didn't bother the staff. We ate lamb chops and bread and dripping with a side dish of cheese and tomato and peaches and apricots off the garden, and who could forget Choko's, that's how tight things were in the 50's! Nobody had a TV in the burbs until the 1960's like the bank manager that lived up the street. I had to chat up his daughter to get a look! (at the TV).
By the time we hit the 70's I had made the 5" TV (colour!!!) and had an Astor 17" that Ian probably fixed once or twice!!
I think Aunty Jack was trying to hold the colour back "I cant hold it Arfer!!!"or something, and it went from B/W to glorious colour.
Fred..

"Aunty Jack was trying to hold the colour back"

You got it, but he fails. Kid Eager (Garry McDonald) is most susceptible to the colour disease, and turns into a green jelly. Thin Arthur (Rory O'Donoghue) goes to colour straight away, but doesn't suffer for it. Aunty Jack (Grahame Bond) resists for a while but also goes to colour.

Thanks STC I had not seen that for ..er..um..(counts on fingers) 43 years on our B/W Astor.
It was lost a bit on a B/W, but when we upgraded to a AWA 21" color was amazing!
That lasted 21 years until the Horizontal output transistor thing failed in a cloud of smoke so we upgraded again to a NEC in 2001 which is still going fine with a STB. We don't watch TV that much, i'm too busy writing and hobbies. Our kids think we are mad. They and their kids walk around clutching their smartphones and have TVs the size of a drive in screen, the bloody things scare me!
We will be watching Annabelle to night and nodding our heads.
Fred.

Fred
I also watched it in B&W but can't at the moment remember the brand of the TV but it was all valves.
What I do remember is that the raster lines on a B&W set went from from solid lines to what I can only call wriggly lines, seen close up to the screen and not at all visible at normal viewing distance. Purely academic but would be interested to know the cause.

Many B&W TVs had poor interlace, meaning the line structure was more visible.

I don't think interlacing was the problem as the lines (apart from the "wriggles") were straight, parallel and evenly spaced. The "wriggles" had a wavelength of 1 or 2 line widths from what I can remember, ie quite fine so not visible at normal viewing distance.

If the space between the upper and lower envelopes of the AM wave forms in the link, are filled in, this about what it looked like.

https://www.google.com.au/search?q=amplitude+modulation+waveform+envelope...

Not suggesting that it is anything to do with amplitude modulation; just the closest I can find online for what it looked like. I guess the effect would have to be derived from some part of colour information on the signal, as process by a monochrome set.

Off topic, but what you are referring to I think is the colour subcarrier information which a B&W TV does not remove from the video.

I thought you were saying that the line structure was coarser and the lines more visible on the B&W signal. If the interlace is poor, this is exactly what happens. Interlace (when it's working) moves the raster up and down on alternate fields so that the gap between the scanning lines gets filled in.

Many valve-based TVs had sub-optimal interlace. The most common cause was crosstalk of the horizontal scan signal coupling from the horizontal to the vertical scan coils in the yoke. This large signal would then get coupled back into the vertical oscillator and swamp the interlace on the sync pulses. Various techniques were used to reduce this crosstalk, including balancing the drive to the yoke coils, horizontal and/or vertical.

ST830 is not talking about “teletext “ info on the first half dozen lines is he?.

I was a radio apprentice at that time and was working for an electrical goods retailer.
They sold the Healing C211 CTV model at the time.
I repaired and aligned them in customers homes.
They were horribly unreliable and the quality control was not great.
They often were dead on arrival so we had to unpack and check them before delivery. They performed well once all their ills were sorted out.

I remember watching the Aunty Jack show with the colour rising up from below while they tried to push it back down. Very funny at the time.

WRT the wriggly lines on B&W sets I think what you were seeing was the unfiltered 4.43 Colour subcarrier pattern. On colour sets this was notch filtered out of the luminance path.

Ian, Johnny & Irext

Thanks for these suggestions. Might be helpful for someone trying to understand what might be thought to be a problem with a set they are working on.
