i4yfc.fabri,

Check out the SLC9 page under technical for Betamax models under the heading "irregular rewind/review."

It is likely to be due to increased friction due to wear on the upper drum.

You can use an ink rubber to scruff up the surface of the upper drum to cure this issue but take care to move the heads out of the way at the same time.

I have also used cleaning pads we call JEX pads (CLEANING SUPPLIES) here to do the same job.

I have 2 SL-F1 that still work very well except for one little problem:

When I rewind a tape i often notice an annoying phenomenon as if the tape sticks and jumps off producing a series of tears: "strap" - "strap" - "strap" .... I have noticed that some brands of tape they do it more and others less, for example some Sony do it less while the Dupont do it a lot. It resembles the Stiking phenomenon.

In some cases the ribbon transport stops completely.

What can be done?

Hello i need a help please.

C9 does not eat the cassette.

The microswitches are OK.

Display and tunes led not light on. When turned C9 on, the mechanica moves and the heads second rotate. Power led and frame lighting.

What to focus on, please?

When the DC Dc converter is bad, it only just doesn't go on display?...others should work, yes?

Thank you wery much.

Hi all

Would someone have a hard copy of the SL-HF100 service manual looking for the actual manual and not one downloaded from the net .

Thanks in advance

Mark, I have a PSU for the SL-3000. Not sure what the pinout is though.

Zane303,

Does your C7 eject the tape?

I'd recommend changing all the belts as they are likely 40 years old. New belts, with their 'youthful' firmness provide more torque for the aging mechanism and will certainly help waken the machine up, making it operate better!

I have a question about the Sony C6:

The clock display is probably about 60% brightness of what it should be. Is there anything I can do to restore the display to full illuminance?

Hi! I am new to this site.

I just bought a SL-3000, but it came without psu. Does anybody know the pin out of the 4 pin DC connector which is on the right hand of the recorder?

Zane303;

Sitting for that long it's more than likely a belt or rubber idler slipping.These models are not only very heavy but have numerous belt's too.If they are NOT stretched (like soft elastic)or hard and cracked/split they can be refreshed with 120 grit paper and also a soak with washing up liquid helps too.Keep isopropyl alcohol away from any rubber though as it will dry it out.

I would also check the electrolytic caps in the PSU too as when they go high ESR they take out other components which can be a pain for some to source.

Good luck....................Kevin

Hi , i have a Sony SL-C7EC that has not been used for 15 years . When i turn it on everything works fine but when i put a tape in it starts doing a humming noise ( like a tape rewind noise ) . this noise noise fluctuates from high pitch gradually to low pitch . the tape does not need to be re-winded and i cannot play the tape . any idea what this is ?

Success!

You were right, Kevin. It was that .33uf 25v blue Sanyo capacitor that was causing the tracking centering problem. I replaced it with a .33 35v tantalum capacitor and it's working great now. Also the PSU caps arrived so I replaced all of them too.

One thing I noticed though was on the video board, 1 of the 1000uf 10v electrolytics was leaking onto the board and traces. Removed, board cleaned, traces repaired and new cap installed. All working great (touch wood) I'm going to leave it on test for the day just to make sure all is ok. All that needs to be replaced now is the front button membrane thing, but I doubt they're available now. Hey-ho.

Thanks Kevin!

Thank you Kevin. That's most helpful! I'm waiting for some replacement electrolytic capacitors to arrive for the PSU, so whilst I'm fitting those I'll mark the pot in its original position and give it a tweak. I'll change the blue Sanyo cap whilst I'm there too. I'll report back once I've had a proper look at it.

Many thanks again!

Dickie:

I've just had a look and the Adj pot you are after is labelled 'SUB TRACK' and is the first in a row of 4 at the top of the servo board to the left.It's level with the top board red screw you have to remove (one of three) to pivot up that board.Make sure when you try adjusting this you put the vcr's outer tracking control to the center.If it still does'nt eliminate all off tracking noise.You may have tape guide alignment issues.There is also a light blue Sanyo made cap on that board (near those 4 pot's).On some VTC 5000 's and 5150's these have gone bad causing non responsive tracking adjustment issues. Not seen that on any 6500's yet though.

Thanks Kevin,

You have given me somewhere to start, i'll first refresh the caps in the PSU. and take it from there..

Reagrds,

Steve
