In the service manual it states that there are two servo plates ..

The SS-11 and JR-1 boards

I can not locate the torsion potentiometer.

On the plate the potentiometers are marked as RV ..

What is the potentiometer to adjust?

I know from experience this happens on the SLHF950 and is down to the failing of the bias transformer on the sound area of the board.

It's usually grey in colour and has a few pins on it's base.

It could well be the issue with your c5.

Weber1600:

You most definitely have a piece of grit or foreign body somewhere along the tape path.

I would look at the area at the upper parts of the tape path as that is where the scoring is occurring.

be careful of those very fragile video heads located around the silver head drum slot.

The back tension to this model is 48gcm and is adjusted by a torque pot on the servo board.

If it isn't EXACT the trick play modes won't work very well, if at all.

Hi Guys

Does anyone have a spares Toshiba V5470B or know of one kicking around for spare parts?

The reason I ask is I've been sent one to repair and so far it's going pretty good.

Someone though has removed the top assembly to the head drum that has two ceramic spring loaded fingers to hold the tape down around the centre of the head drum.

The whole assembly is gone. You can see the new/clean metal where it once was screwed in place.

If not I will see if a Sanyo VTC 9300 one is similar as the inside is very similar to this model and the Sony C6.

Cheers in advance......................Kevin

Hello...

My Sony sl c9 marks the tapes on the top of the tape.

It makes a horizontal line ..

By opening the tape flap you can clearly see the horizontal mark on the top of the tape.

Once the tape is inserted in the video, when you put it in the horizontal mark

begins at the height of the rounded black tensor that is located on the left ...

I hope to have help for the adjustment and that the rest of the functions of the video are operative.

Hola...

Mi Sony sl c9 marca las cintas en la parte alta de la cinta..

Hace una raya horizontal ..

Abriendo la trampilla de la cinta se puede ver claramente la marca horizontal en la parte de arriba de la cinta..

Una vez introducida la cinta en el vídeo , al ponerlo el Play la marca horizontal

comienza a la altura del tensor de color negro redondeado que está situado a la parte izquierda...

Espero tener ayuda para el ajuste ya que el resto de funciones del vídeo están operativas...

Hi guys:

Does anyone have the service manual for a Toshiba V5470B?

I'm working on one and there is one belt I cannot seem to find were it goes (bearing in mind three were missing and two like glue. It's the smallest diameter thinnest one.

Also there's a spring to the bottom right of the cassette tray assembly.

This spring has come unattached at the inner side and I cannot see where it goes.

Cheers.................Kevin

Hi Noel please just remind me of your website.It should be in my contact list,but last year my account got hacked, can you also remind me of the heads part number for ,SL-HF 950 DSR--- comes to mind. Kevin I really must take more care when writing posts my spelling is not great and my,Grammar and punctuation could be better.I guess the secret is taking more time. I notice Kevin you also visit Paul Stennings vintage radio website it is very useful and interesting some of the,restorations are painstakingly done .

Kevin,

For your information the tape load motor from the SLV777 or SLV815 VHS machines of that era (late 1980s) can be used as a replacement for the SLHF950 tray motors. Slightly bigger mounting screws so mount holes need to be wider but the plastic drive gear on the shaft and motor dimensions are otherwise the same. Motor tags are 90 degrees off but can be bent to suit. The motor magnetic shield can be swapped over as well. (same motor case diameters)

regards Noel

Noel:

I've had to sort two out like that already. When they fall off or loose contact the hatch lifts up and keeps clacking until it goes down on it's own.

I re glued them back and then hot melted a plastic shim to go over the whole attached part area to ensure it never happens again.

This with the broken sled track is going to get more common over time ,so I always check both those areas out now too.

Thanks for the update though :)

..........Kevin
