Wonderful machines here, the Video Showcase especially. I've never seen a CVC machine myself, just read about it in my VCR textbooks, Television magazines etc. Look forward to seeing more on the repairs, hopefully.
The VP-100 is a great looking machine, I can't wait to see it working. I bought a reel to reel about 3 years ago. The audio was there but the mechanism did'nt run. so I assumed the belts had broke. (it used 3 of them). I took the top off and all of the belts had melted all over the mechanism. I put the top back on and stuck it on a shelf. It's still there. LOL.
I remember using one of those CVC machines at school in the mid 80s -and it was old hat then. The camera was dreadful in low light like you said and suffered from trails with bright lights. I think I still have a school project I filmed on one transferred to vhs. The image quality was pretty poor even by mid 80s standards if I recall.
Hi! I also have a Grundig CVC tape recorder! I changed a lot of :) capacitors! The problem was that the copper under the capacitors was broken.THIS WAS THE SMALLEST CASSETTE FORMAT AT THE TIME! I really liked!
I've been working on the VP100 and found exactly one slightly out of spec capacitor. But I think I'm closer to finding the real cause of the fault, wait for Part 2...
Grundig apparently always used loosing formats: SVR, V2000, CVC, and they had their DC international audio cassettes, and several weird dictaphone cartridges that nobody else used. I wonder why they were so stubborn...
That first technicolor machine looks so interesting, and its so clean for its age. If the belts can be sorted out maybe record or dub a sound track over the original sound, a single 1khz tone. You could listen on playback to see if the capstan is jumping by the tone jump. A strobe disk for 50hz mains would be handy for the video drum, if it divides. That black goo is so nasty, no fun at all.
i hate cleaning dissolved belts... its standard in Philips Reel-to-reel tape recorders ;) i have that portable CVC video recorder but my is UHER but i see its the same
It really makes you wonder what sorts of conversations the engineers were having amongst themselves/upper management when this device was being created. In some products it's obvious: the entire Betacam lineage seems to have been overengineered within an inch of its life; a gentle breeze at an inopportune time would most likely wreak havoc with a DVCPRO deck, but with this... I'm not quite so sure. Curious as to hear your opinion on some of the design decisions that were made - do they have any redeeming qualities? Are they otherwise novel ideas, hampered by xyz?
It's nice the way the tape vacates one spool to make room on the other, like an audio cassette. Few other video formats do that (U-matic does). The lacing mechanism was the big problem with the Technicolor design, which Grundig sorted with the VP100, but by then it was too late to save the format. There will be more on this format shortly, I've been working on the VP100 and also may have something else coming in.
30:59 looking at the mechanism and PCB this was not really made by Grundig. The mechanism with the microswitches gives a strong JVC vibe and the chipset on the PCB is Hitachi and the Electrolytics Made in Japan. If it was a Grundig designed gear the higher level signal chips would be Philips/Valvo or Siemens and the caps Frako or ERO.
Since Funai made the first generation of CVC machines, it's quite likely they were involved in the Grundig model too, but they never marketed that improved version.
Am I mis-remembering, or does the video output pin on those Hirose Camera connectors have a DC offset? (Assuming they're the same as used on VHS portable recorders.) I seem to recall the voltage of the offset is used to signal to the camera whether the machine is in play or record mode, or something??
This is NOT a Hirose Connector on the camera at 20:25. This connector is called Din-AV. It is a 240° 6 pin connector and is the predator to SCART. It was intended for bidirectional signal transfer, but had only enough wires to allow one signal direction at a time. This is why it contained GND, Vid, Aud L+R, a 12V low power supply line and a signal flow direction control line. The control line was meant to signal to the TV when a VCR or other AV source was requesting a playback on screen, to which the TV would turn its DinAV plug from output to input mode, speed up its sync separator latency to avoid flagging on the top of the screen, and display AV or some other program indicator.
@@randomsteve4288That squashed connector is indeed a common DIN plug, but the Camera connector I was referring to is the 14-pin Hirose one, indicated at 1:47 in this video.
There's no value to speak of with the camera. A working CVC recorder is valuable, perhaps £200 - £300 or more. A non-working or untested one is low value, perhaps £20 - £50.
Mr. Video99: Now unfortunately that is a rare machine and I would like to demonstrate it to you but… Mr. Video99’s Child: Delivery! Mr. Video99: Oh! Get’s me every time!
Adjustment of the Tracking Control is usually not necessary when playing tapes recorded on the same machine, but may be required when playing tapes recorded on another machine. I had a Grundig badged CVC Portable (IIRC). Never worked properly! Now polluting the environment in landfill! 💀👎🤣 EDIT: One wonders WHY manufacturers don't design products with EASE OF SERVICING in mind? ANOTHER EDIT: 18:44 The Grundig VP100 appears to be identical to the one I had! I seem to remember I had some Technicolor machines too. YET ANOTHER EDIT: Rubber perishing is a perishing nuisance! ... Particularly when it happens to my RUBBER CLOTHING! 👎😜🤣
Your comment is nonsense. Grundig labelled the machines sold in german speaking countries in german, and machines sold outside germany in english, sometes even italian or french. These export machines may even feature country specific specifications. It is not Grundig's fault that nowadays you can aquire an entirely domestic model outside of Germany or ship it worldwide. The same horrifically narrow minded statement you could have aimed at Sony too, who did label the domestic models in Japanese and only export models in english.
@@randomsteve4288 I'm not from any of those countries, and I only have to walk a few meters to see the German brands I mentioned with nothing but German text. I know Danish is not a big language, but every other brand had English text.
I saw in an issue of I think Popular Science magazine that Elbex, a company I had never heard of but are apparently still around in CCTV and video intercoms, was developing a CVC format camcorder called the Moviemag FX203 that they wanted to get out as early as January 1983, meaning it would have beat the Betamovie and the SF-P3 adaptor for the HR-C3 to market for first camcorder. In reality, of course, it never seems to have come out at all.
