"Step inside the Philips plant in Clayton, Victoria, for a rare behind-the-scenes look at how colour television sets were made in Australia. This clip, from Australian Movie Magazine No. 7436, captures the precision and craftsmanship behind manufacturing these cutting-edge TVs as the nation embraced the shift from black and white to colour."
@ntscuser Interesting film. The modules made for easy replacement are large, I wonder how many were replaced in the field as opposed to standard component replacement we were used to in the UK?

You mean those plug-in modules in the little aluminium cans?
No circuits were ever published by Philips for these, ostensibly because the internal circuit could (and did) change. Rarely if ever replaced.
@irob2345 I notice the sets shown are 110 degree delta CRTs, is this the K9 chassis on which your rare Kreisler is based. Were you ever successful obtaining a CRT?
John.
@irob2345 The way the video suggests, well to me, that the large boards were the modules.
Perhaps not explained deeply enough but for a customer intended video perhaps that’s ok.
For those who didn’t get to see manufacturing, these types of videos are very interesting.

No CRT yet. Yes that's the K9 that the Kriesler 59-01 was based on. They both had VHF only turret tuners. That's hard to see in the video.
I have since picked up a Philips K9 - same model as in the video. CRT is good. It's strapped to the stair climbing trolley awaiting its move up the stairs from the garage.
Considering that hundreds of thousands of Philips K9s and Kriesler 59-01s were made, there are very few of them still around.
One interesting sidelight is, although Philips didn't publish schematics for the can encased plug-in modules, Kriesler did. They were built on cards about 12cm x 8cm and used a single in line PCB pin connector that came out both sides of the motherboard. This enabled you to service the module by plugging it into the print side of the PCB. Sharp (who also built colour TVs in Australia, at Fairfield in western Sydney) copied the idea.
The pinouts of the modules exactly matched that of the Philips ones. This made it possible to service the Philips modules using the Kriesler schematics - something that Philips actively discouraged!
The SMPS power supply in the Oz built K9 was basically the Euro "AV" version, hence the chassis was not live on Oz K9s.
Kriesler redesigned that power supply - although they had reliability issues with the board connectors, the Kriesler version made that TV bulletproof. I had a case with a TV in a seaside location where the loom to the convergence neck assembly had come unclipped and was resting on the EHT connector. Turning the TV on would reveal an almost inaudible "tic .... tic .... tic" as the EHT started to flash over to the convergence wiring. That power supply was detecting the arc and shutting down so quickly that absolutely no damage was done. All I had to do was clip the loom back in place and perfect operation was restored. I did of course give the EHT connector a good clean.
Were that all TVs were so forgiving!
Oh BTW, that plant shown in the video was the (not so old) Astor plant at Clayton, a Melbourne suburb. Philips had everything they needed to build K9s already there.
@irob2345 That was a very interesting video. Our native K9's made here in New Zealand also used the isolated SMPS as well. I wonder how closely the sets were made specification wise between Aus and NZ? They were and still are a great set. I have a couple in the collection and the 26 inch version is in regular use.
