Re: S-Video out N1700

Sorry for the English.

That looks great. Can you tell me - I see a custom prototype PCB with 2 resistors . Is this just to link the Y-C cables to an s-video plug?

I assume these are 75 ohm 0.25W resistors, 1 for Y, 1 for C ?

Re: Probleem met Betamax SL-HF950

Hello everyone. I think I have the same problem with my HF 950 (head drum spins ups, then slows to a stop which causes a shutdown). I'm sorry, I don't understand Dutch and google translate is struggling with the technical translations. Could someone translate the solution into English for me? Rob

Re: Het Ghhrumsound SVR avontuur

Hello ! I think this was discussed somewhere in this forum already, but couldn't find it. After getting my SVR 4004 (GB) to run again, I have what I think is a back-tension issue as the picture almost looses tracking every 15 seconds or-so. I was trying to understand how the LED on the back-tension ...

Re: Het Ghhrumsound SVR avontuur

Hello from England! Thank you for writing your SVR adventure. Early this summer, I was asked to look at 3 non-working SVR 4004 machines. With great thanks to this forum, all three are now beginning to work. Machine 1: Y- (luma) board smoked when attempting to play - shorted tantalum (C715). MotorEle...

Re: User Manuals VCR en VCC machines

Hello Otto.

Dutch or German manuals would be better than nothing. Are these scanned manuals or paper?

I may only need the schematics/diagrams for a couple of areas.

Rob.

Re: User Manuals VCR en VCC machines

Hello everybody. My friend and I have recently bought a collection of VCR and (Grundig) SVR machines which we are in the process of renovating. One of them is the very rare N1520 editing machine. We have a fault (picture is in black & white only) and we are looking for the service manual. Does anyon...

Re: VR2414 - Possible DTF problem?

Hi Mae,

Unfortunately, the sticker on the back of my VR2414 had been removed when I received the machine. Is this the only place to find the information? I recall the N1502/1700/1702 had additional stickers inside the machine.

Re: VR2414 - Possible DTF problem?

I will try that Gromsound and let you all know. I am still learning with these machines and am finding that when they are working, they all have different abilities to play very old VCC tapes. I have a VR2324, VR2334 and (no laughing) a Grundig Super 2x4 which all work now. I do find that some very ...

Re: VR2414 - Possible DTF problem?

Thanks Dominic. Yes, I did have to (gently) clean the DTF contacts/brushes. As you say, they were black on the tips, but now they are silver and shiny after cleaning with iso-propyl alcohol. Thanks for the translation. I would have thought I could measure the actuator voltages without going into thi...

Re: VR2414 - Possible DTF problem?

Hello Gromsound and everyone. Today I checked further on my VR2414 DTF issue. I too cannot recognize the strange sound on my video while the tape is playing. Here is what I have done: - I checked that the upper head drum can spin freely under the DTF bridge with the mains power unplugged - YES. ALL ...

Re: VR2414 - Possible DTF problem?

Thanks Gromsound. I do seem to choose the difficult ones ! Can I confirm with you that the sound I hear on the YouTube video is the DTF actuators firing? If they are working, do you agree the fault is probably in the electronics of the DTF circuits on the A610 board that is folded in 3 pieces on the...

VR2414 - Possible DTF problem?

Hello everyone. Thank you for your help last year in fixing my VCC machines. With your help I now have 2 working Video 2000 machines. Last week I came across a Philips VR2414 which I wanted to rescue. I have: - replaced the X2 mains capacitor (which had exploded!) - cleaned the code disc, DTF contac...

Re: Poor video on VR2220

Thank you Gromsound.

If the plug/socket cleaning does not work, is it possible to try each board in turn in a working VR2324 to isolate the problem?

Also, do you advise against changing the dropout compensator? I thought that may be the problem.

Rob
