I dissasemble the whole bridge million pieces(didn't have time to take picture while doing it), and clean everything and assemble back again and aligned according to manual. And now, everything is working as it should. Don't know exactly what the problem was, probably some misalignment in timings somwhere, but when I was lookling and comparing to the other bridge everything was same...

JVC VCR HR-S9850 fast FF/REW & Stop problem
Hi, when tape is doing fast FF or fast REW and I hit stop, right reel stops almost instantly, and left reel is still spinning for second or maybe half second. And you can hear that crackling when tape stops and it wrinkle a bit on the side where pinch roller is I think before it. Then I do a little REW or FF to tight the track back because in that moment it became loose on pullies. I can't find out what's going on and how to fix it, I tried to replace that left brake arm but still same, everything is clean in vcr, new pinch roller, belts, felts. Any idea what this problem could be ?

IC chip for VCR JVC HR-S9850
Hi, I accidently burned motor for head drum on my vcr, and I need to replace it. But I can't manage to find it anywhere. Can someone help. I attached picture....

I searched now on aliexpress but I can't find anything with midpoint AC10K 6pin 23mm shaft.
does it matter if there is no midpoint, will it work normally without it if I put them instead of this original ones ?Last edited by Thermaltake; 04-10-2025, 02:31 AM.Leave a comment:

ah, I will need new AC10K then with midpoint because this was for some reason without midpoint(center). I'll try and search it myself if you don't have time.Leave a comment:

Can I use that AC10K instead of B503 6pin ? They are both without center pin.
B50K link is now giving me 404 errorLeave a comment:

On V8000 there are not many rubber stuff, it's mostly mechanic. One belt which is okay I inspect it, and pinch roller which is also like new. I just refresh them a little.
But on my other VCRs I replace old rubbers with new one if they are broken or worn out....Leave a comment:

Update on my V8000.
Around 50 electrolytic capacitors​ were replaced plus some smd electrolytic caps too. Corrected a lot of bad solder on various boards in video section, they were the reason why front inputs were not working. Now everything is working as it should.Leave a comment:

I assume this first one B50K would be ok to put in place of those two, right ?Leave a comment:

Thank you.
There also 2x 3B503x with 6 pin and midpoint for FX on the Stereo Aux Returns.Leave a comment:

Thanks.
On B50K - this one on link have plastic threads on the bottom of the pot. Mine don't, and I think that will make problems when I wan't to close that metal cover of mixer.Last edited by Thermaltake; 03-12-2025, 11:45 PM.Leave a comment:

Thanks!
I calculated around 44 capacitors will be changed on vcr
hope everything went well. I even corrected some factory faults on it, and now only cap changing is left. I'll let you know, and post some pictures if that's ok....

I am curious because I am going to buy them, but not sure if they should be normal or low esr...Leave a comment:

Damn I am blind.... thanks!
Low esr can go there ? And on that board when I replace those big caps, can all be low esr ?...Last edited by Thermaltake; 02-01-2025, 09:10 AM.Leave a comment:

One more help.
I was trying to look in my V8000 at capacitor physically in video board but it's deep under the doughter boards and I can't see it's values. In manual it's under C3768, can someone see in manual or find somehow the values ? I was looking but nothing in the manual seems to point out what value that capacitor is.Leave a comment:
