60's black & white dual standard sets were problematic enough, the colour ones were on a whole different level again! I had a dual standard Philips Colour set back in the early 90's, I couldn't do a thing with it so I scrapped it. Interesting idea about the 405 line colour. It would possibly be doable but it would probably be easier to get an old US set as Aurora do a 625 line PAL to 525 line NSTC converter, and play let's pretend, lol. As I said on another thread back in the 70's I had a 405 line set with a UHF Tuner & a reversed picture polarity diode (the correct description eludes me - another senior moment, LOL) that gave a good picture on 625 line signals if you banked the horizontal hold right over and tweaked the height. OT I know but I remember the old man telling me that he watched French transmissions on 405 line in the summer with the skip in Birmingham on Band 1, IIRC they used 900 ish lines & it worked on 405 lines by missing alternate lines out. Later on (70's again) you could get PTT 1 & 2 & ZDF on UHF in the summer in Lincolnshire but only silent as the carrier frequency for audio was different on the continent.

France was odd in having a 819 line system which was heavy on bandwidth, & followed by SECAM which was also technically interesting.

Thanks for the interesting link Steve.

VHF used to pickup various electrical interference, lights motors etc that's my abiding memory of TV in Australia, that and a diabolical ABC signal on a curly wurly onset aerial ;-)

Channel 0 (when Channel 10 started) and Channel 2 (ABC) were always affected by interference. I think it's because they were on VHF low band, I stand to be corrected on this. Channels 7 & 9 were better as they were on VHF high band, I think.

Channels 7 & 9 were better as they were on VHF high band, I think. Yes, that right. Belmont in East Lincs had Anglia on Channel 7 and the BBC on Channel 13 for exactly that reason. Prior to Belmont's construction North & East Lincolnshire had to rely on fringe reception from Home Moss & Sutton Coldfield, which meant that, in the summer months co channel interference was a serious problem, particularly on the band 1 BBC channels. Mind you I could get Yorkshire from Emley Moor as clear as a bell on just a dipole aerial in my bedroom on band 3. Happy memories. 😀👍

I was impressed that the first Sinclair portable TV could receive most 525 & 625 broadcasts, considering how small it was.

Still going strong. C4 News tonight. Again the patterning is just a result of photographing with the iPad.

I actually saw a repair shop here in Lisbon that also sells vintage TVs. If I can remember where it is, I'll take a picture next time we walk past. I know we found it the same day we found the English bookshop near the embassy. (Not that I've had occasion to go to the embassy, we were actually having a wander on the way home from the hairdressers...)

That would be interesting to see. Just as an aside, friend of mine took photos of a shop in Albania selling vintage TV's & Radios a couple of years ago, so they are still about. Even in the UK thankfully these sort of shops still exist. Burketts on Steep Hill in Lincoln has always been a Mecca for old radios & spare parts as far as I know, it was still trading a couple of years back.
The funny thing with my GEC set is that I wanted to get one for sentimental reasons because it is the same model as the first set I ever got going with my Dad as a pre-teen back in the early 70's. Despite the original one being relatively a lot younger and long gone, this one has a better picture than the other one used to, which when you consider the age of the tube is remarkable.

I thought I recognised that as a GEC, the same as my parents used to rent in the 1960's.

Good sets & simple to work on . My current one is a GEC BT302, the one I had in the 70's was a GEC BT303 which looked identical apart from being the high gain version for fringe reception & boy could it pull weak signals in, Yorkshire from Emley Moor all the time on a dipole in my bedroom in East Lincs!
