Left for dead "parts bin" Philips N1700 1978 video recorder.

[@Meepsmusic63]

Hey Colin, its always an adventure/ learning curve watching one of ya videos, and i dont comment a lot but i always look out for what ya been up to, phenomenal work your doing on those old 1700's. that video was the first video i ever owned BTW in 1983 and i bought it from my uncle who had swapped over to VHS at the time, I found it fascinating to watch tv in the uk when all the tv stations where shut down at 3am in the morning on terrestrial TV at that time. anyway, fantastic detective work, im so impressed. imagine the look on a modern tv engineers face if ya called him or her out to repair one of those things? lol.. and well done, greetings from plymouth devon

[@hoffmannolsen]

Great show! Was so caught up, that i forgot an appointment.

[@markpirateuk]

What a mammoth repair, I really admire your patience, good luck finding some decent heads, I guess the only source is another N1700.......

[@lorevids_]

This was once again great to watch. There's something oddly satisfying about bringing old stuff back alive. Brings back memories, I got my first (broken) n1700 from my school when I was 13 and I managed to fix it. Addicted ever since 😊. Now all that is left is to get that #2 working, still curious if it's that bracket pivot thingy. I did get a little scared halfway this video, oh no is he turning #2 into a donor...

[@video99couk]

I'll be putting the untested main panel into #2 (hopefully will have good colour on that one) and the good delay line. Then just needs heads before working on it again.

Must be nice to have so many spare parts laying around 🙂 Nice video! Thanks for posting.

I'm not a engineer , So I really have no Idea what you are doing - Buy I have to say, that The engineering and development it took to make those machines always astonishes me and the fact that it once adorned someone's living room ,I hate it when we just throw them away for something new, and I also have to say that I admire your resolve in getting a working machine . . I would have loved one of those machines but our family could never have afforded one . Thanks and Ive subscribed .

I interviewed one of the engineers who developed this format, see: kzbin.info/www/bejne/gpmuipt5edidsKs

[@frankowalker4662]

That was an exciting video. It was like one of those old B&W serials where you got a cliff-hanger at the end of each episode.

[@zhaohaigaogu7821]

💯👍The parts were in a more complicated condition than other VCRs.🧐

[@timothyrdunning]

Really enjoyed this video Colin.

[@masoudmontazery907]

Good luck sir

[@IainDavies-z2l]

I was thinking don't worry about damaging the delay line getting out that module if you were never going to record PAL broadcasts, but didn't realise it was on the output.

[@TTVEaGMXde]

The single layer copper coil delays Luma because the color would come later than Luma due to the low frequency response (

[@alphabeets]

Crikey, what a tedious job that turned out to be!

[@video99couk]

It was a bit long, and believe me the edited version is a small fraction of the actual time spent on it. I need to do a shorter video next week!

[@mikaelgranquist821]

How many Philips VCR (1500/1700) video recorders do you have, including scrap machines? You must have at least 20-30 of them in your stock pile in all your sheds! You always seems to find spare parts when ever you need!🤔

[@video99couk]

Not counted them but probably that sort of number.

[@mikaelgranquist821]

@@video99couk Wow!😃 How many are fully working?

[@WolfmanDude]

Do you have a dial gauge? It would be interesting to measure the difference in head protrusion between the worn out and new head drum. I think you should absolutely measure a difference, maybe you could use these measurements in the future for fault finding. So you dont have to guess if a head is worn out :)

[@video99couk]

I have one somewhere, but I would be quite nervous about putting the gauge on the head tip. One wrong move and it would be all over.

[@WolfmanDude]

@@video99couk I just read that protrusion should be 50um for a new head and everything under 15um is bad (for VHS). This is fascinating, it would be soo useful to have a concrete number to evaluate head wear. I will try measuring on a crappy VCR tomorrow.

[@rsuryase]

Is Electrolube Platenclene similar to Rubber Renue?

[@video99couk]

Yes I would think they are similar products.

[@ahmedaljibory691]

How are you my friend? I have a Betamax T7 video cassette, the colors are broken, the picture is black and white. How can I fix the color not showing up? Please help me find the problem. Thank you very much.

[@crashbandicoot4everr]

Fixing chroma faults on early multi system VCRs like this one can be a nightmare. Have you tried PAL, SECAM and NTSC tapes?

[@livinlifetothefullest2750]

If only there was a way rebuild or make your own head tips.if only...

[@video99couk]

In theory, you could repair head drums by swapping head chips from one drum to another. In practice, alignment is almost impossible.

[@livinlifetothefullest2750]

@video99couk well the Sony betamax early model manuals did have a didheral adjustment assuming the factory didn't have the heads precisely adjusted or an ultra rate scenario where the head had slightly crept out of adjustment despite the lock glue used.

[@Matt_Quinn-Personal_Account]

@@video99couk Somewhere buried deep in the interminable pile of 'Television' magazines is an article on doing just that. I seem to recall reading it one lunchtime over a cheese roll and a can of Coke! - Personally I have my doubts; Maybe something that could be done on some of the old EIAJ or Sony2100 machines; but even then... Could be worth doing as an experiment I supposed.

[@TelevisieArchief]

Hi Colin, if need some spare parts please Pm me.

[@video99couk]

Always was N1502 and N1700 video heads above all.
