Panasonic NV-HS860 / NV-HS960 Drum Head Cylinder
Hi all, I've been working on a NV-HS960 Panasonic machine which has been stored away for some time.
Upon powering up the unit everything was ok for a moment until a loud sound presented itself (sounding like friction) after a few minutes of playing with the functions but mainly came from playback. The drive belt looks to be in good order and not loose. The drum moves smoothly by hand and the heads have been cleaned. The sound only slows to a halt when a tape is ejected leading me to believe it is the head mechanism/drum. I think I have exhausted most routes and now might need to look for another head unit to replace it? I note that the 860 and 960 both use the same drum type but are there any others which might be easier to find for parts? The head unit is labeled VXP2049 on the 860 and VXP2050 on the 960 but have not had any luck in finding replacements, I have tried donberg and they don't have anything. Any help would be very useful. |

When you hear the friction sound if you pause the tape? The sound exist or not?

So far everything I can gather points me towards the bearings inside the cylinder and now it appears the picture is not being picked up well at all including the audio which both are intermittent, more off than on, fast forwarding shows the image but playback is not good. Having come this far I decided to look inside the head as I thought the friction sound could be from debris or similar. That said, once assembled this is when I am finding the audio and video has started to drop badly. I've been told I might be able to source parts from a 900model which looks like it uses an interchangable drum. |

The 900 is not the same drum sadly. 960 has amorphous chips plus a flying erase that the one from the 860 does not have.
Im wondering if you have failing PSU capacitors. They can cause all sorts of weird noises from the head drum motor and capstan too as well as bad picture and sound. Just a thoughtful and worth doing anyway. |

Thanks for the input, I'm still looking to source a head replacement and if there is no progress from that I will report back.

Where is the static discharge brush? It might need a drop of something like WD-40 on it.
I can not see how the upper drum assembly could cause a bearing like sound. Just a thought, it might be the rotary transformer windings floating loose in its assembly. Wayne. |

Agree with Ian - unusually capacitor problems can cause all sorts of odd sounds, but I usually found the capstan motor was the one that growled - easily proved by pressing Pause. I suspect they will need changing anyway at this age.

Re: Panasonic NV-HS860 / NV-HS960 Drum Head Cylinder
Hi! I was working on my Panasonic NV-F66BR with a similar problem: when the head started rotating, after a few minutes (5-10), a constant sound would start to be heard that wouldn't stop until the head did not stop rotating.
I found the solution in this thread: https://www.vintage-radio.net/forum/...ad.php?t=90961 . Removing the small circular metal plate held by 3 torx screws and lubing with one drop of oil worked perfect for me. |
