I've been given a Philips N1700 VCR-LP machine. Let's see if we can get it going. The mechanism is very similar to the N1502 model.
Also, an alternative design for taking digital audio from Sony PCM-F1 decoders includinig PCM-501ES and PCM-701ES.

I found a pre-recorded tape for this type of recorder years ago, sitting outside on a window sill of a second-hand shop that to my knowledge only sold furniture, paintings, etc. It was a bit dirty but otherwise fine. Took it home, never could play it back of course due to lack of a player. It still has the label on it of the video rental house it belonged to.

@video99couk 2 года назад

I've never seen a pre-recorded N1500 tape (I'm pretty sure it won't be the later N1700, but the label would say so if it is). If you still have it, I could try it out.

Ha I didn't know the tool was used to clean that tape guide. I learned something today I guess. I think they put it in there to adjust the modulator. I took out the one that I got with my 1700, it was my only non-conductive screw driver for years. 😃 My 1700 had the rewind problem too by the way. Drove me nuts! I even tried putting a little grease on the spools of a cassette to improve things. Obviously that didn't help.

Philips had some really stylish products back in the 70's Hi-Fi units looked very fashionable too.

@video99couk 3 года назад

Philips equipment can be quite smart. However sometimes the logic behind the way Philips equipment is operated is baffling. These machines are quite logical, if strangely labelled.

@g7mzh 2 года назад

The 1700 gave one of the best - if not the best - picture quality of all the domestic VCRs. Certainly better than VHS (but what isn't?).

@video99couk 2 года назад

Certainly VHS is a very low bar. I think a top notch Beta is probably better than N1700 (better servos), but they're in similar territory.

@mspysu79 3 года назад

Awesome to see another Philips machine come to life. Nope have never seen another machine move the head drum like that when threading the tape. Cool to see the boards for the PSM/SPDIF boards, do you know if Brian is willing to release his circuit, I have a 501 I would love to fit with a card.

@video99couk 3 года назад

Brian has said he's happy for me to use his design. So once I've built and tested one, I can release all the details.

@zx8401ztv 3 года назад

Well that works really well now, well done :-D The picture looks good, likely better than the old piano key vhs machines. Philips made front loading vhs machines that had the same odd line effect on the screen with no fm from the heads. I can see why there vhs machines had a similar line effect. I'm talking about the machines with the horrible clip and screw that held the video head drum in place. Not a machine i would want to change the heads on :-(.

@video99couk 3 года назад

That's right, some Philips VHS machines did give a similar effect, I had a VHS HiFi Charlie deck which would do that.

@crashbandicoot4everr 3 года назад

@@video99couk My Grundig VS-310 VHS isn't different. Same effect. I guess they all use similar ICs.

@zx8401ztv 3 года назад

@@video99couk Another thing i remembered is when you applied power to the machine, it would mess about with the deck and forward fast then rewind, then load and unload. And if you held a certain button or buttons down when applying power, it showed the number of hours it was used for. Philips often went too far with there designs lol.

RE: Comb filter. If your TBC has separate chroma and luminance processing, an SVideo connection will yield better image quality. The Chroma is separated before recording on consumer (color under) VTRs. And the chroma is processed separately on playback before the final re-combine with the luminance. So if the TBC has a separate chroma path, why re-combine the chroma at the VTR only to have to separate it again in the TBC? It's not a case of a better comb filter in the TBC, it's a case of a comb filter or none, which is cleaner. Now if your TBC is full composite processing, then it really doesn't matter.

@video99couk 3 года назад

Absolutely, I use S-Video connections where available on all my equipment. However the N1700 wasn't built with S-Video, it's a case of modifying it to add it, and when I tried that circuit I didn't like the results, there was a chroma offset and noise. So I decided to let the digital comb filter handle it instead in just this case.

@TigerBoyRS 2 года назад

Colin, please enlight me on these one: What's with all that can boxes around groups of electronic components? Is it just RF shielding? Overkill or real needed, mind the Era? Thanks, keep on the good work. Cheers 🇵🇹

@video99couk 2 года назад

RF shielding primarily, but it also acted as a way to support the small PCB modules. The idea was that you could swap out a defective module quickly to assist with easy maintenance, in stark contrast to the older N1500 model which was horrible to work on.

Would you know what can cause a the loading mechanism in a Beta player to stay stuck or not load the tape (am not sure which one)??

Really depends on what model.

Hi, how do you remove the cassette loading part? It looks easy but I just can't figure it out and don't want to break it.

@video99couk 2 года назад

Could you be a bit more precise about the part you need to remove? The top carriage comes off very easily (it's in the instruction book!) but deeper parts of the mechanism are not trivial.

@SR-vl1kp 2 года назад

@@video99couk Yes the top carriage. It looks easy but still can't figure it out. I don't have an instruction book unfortunately.

Finalmente tenho um. Consegui por a mecânica a funcionar, mas não tenho cassetes gravadas, apenas tenho duas virgens. A avaria que detetei não recebe o sinal de antena rf, mesmo ligando um videogravador em UHF,mas passa o sinal rf de antena mas sem dar para programar os canais do video. Não consegui fazer gravação.

There are plenty of recorded N1700 tapes available on eBay or similar. If you get stuck looking for one, I can probably supply you with something.
