Mike, The pot you're looking for is located (believe it or not) on the board that you see when the top cover is removed .It's position is RV201 and it's located about in the center of the board next to the large printed words DRIVE. It's gonna take a very small screwdriver to access it through the small hole because the side you're looking at is the solder side of the board.If you unfasten the board and tilt it up to the component side the pot is easier to adjust without such a small screwdriver.If you adjust it from the solder side turn it CCW and CW if adjusted from the component side.If I were you I'd adjust it from the component side and mark it BEFORE you do any turning. Turn it a little bit at a time and check to see if the tape starts to be takin up.If the nylon bearing in the the takeup spool isn't worn too bad you should be able to get it to work by the pot adjustment.If the pot won't do it then the only thing you can do is get another reel drive or fix the one by increasing the distance between the rotor and the windings. By the way in addition to the pot being labeled RV201 it says FWD.TORQ. Good luck!

Thanks Dave for the help. Now all I have to do is locate the potentiometer, I'm thinking it is on the board that the reels are on, which I would get to by removal of bottom cover?

Hi mikeThe problem is very common I saved a post from about a year ago I think this should help youHere is is :Re: SL-HFR70. Had the same exact problem with mine. It turned out that wear in the clutch mechanism of the takeup reel made it unable to wind the tape fast enough (esp. towards the end of tapes), therefore creating a tape slack between the capstan and takeup which triggered emergency stop. A quick fix is to increase Forward Torque, there is a potentiometer to adjust this, I can't remember where it is yet it is identified on the board so you should be able to find it. Hope this helps.

Hello, I am having a problem with a Sony SL-HFR70 which I believe is a common problem because I have seen this before. I finally took the cover off and decided to take a look inside. Occasionally, the unit will play for a few seconds, then shut off. I see that the tape is bunching up near the end of the tape path and not feeding into the take up reel like it should which is causing the shut off. There is something in the repair section of this site which addresses a problem similar to this, I believe it said something about a bearing being bad, but it also said that the tape will unspool and hang out when the tape is ejected, and mine is not doing that. Is this just an adjustment that is needed, if so, what needs adjusting? If not answering just for me, please answer for everyone else out here. thank you

Thanks Noel, I will try get hold of a belt kit and look into it, I'm pretty good at taking things apart, (lol aren't we all)so will have a look myself, if no joy then I will refer it to someone more knowledgeable in this particular field, thanks again for the advice it's very much appreciated, Sean

Don,

I've short-circuited things a bit by finding enough standards sites on the Web which agree that whatever the situation in the past, Greece now uses PAL B/G. So however basic your Greek TV might be, if it works off-air it should work with your Beta gear and the latter should also work off-air. It would seem that you have no TV standards problem, but you do have a connection and/or setup problem.

The mystery is that Saudi Arabia uses PAL B/G and something called SECAM B/G. I would be surprised if you had your gear set up for SECAM but not for PAL when you lived there. It should work with the settings you used in Saudi Arabia. PAL B/G is the commonest standard on the planet, whatever the Japanese and Americans might think!

My suggestion would be that you get hold of a PAL tape with something on it, connect the co-axial output to the TV aerial socket with a suitable lead, set the tape to playing and start searching for a signal by whatever means your TV uses. Make sure everything in sight is set to PAL. If your TV directly shows UHF channel numbers, start with Ch35 then go through the rest of the 30s. Failing that you'll just have to go through all channels. If that works then you can turn your attention to finding an off-air signal at the other end of your gear. To that end, it would be useful if you could send me photographs of all the connections in and out of your gear and between the various bits of it, also all thecontrols. Having established RF connections, you can then start on seting up audio/video connections for proper quality. Does your TV have a SCART socket - large, two ranks of pins, square at one end, funny shape at the other?

Good luck, Bill

Just reread your email and saw that you said you checked the belts. Inspecting the belts generally does not tell you how much they have stretched or how sticky (grippy) they are.

Check that the load ring is in the home position (unloaded) before you load the tape. You should hear a solenoid click when you press the tape carriage down and then the load sequence starts. The rubber surface of the drive pulley (between and below the reel spool drives) that loads and unloads the tape is the most prone to failure. It gets worn and shiny. A later modification called a rewind kit undated the design to overcome this typical fault. (ie load unload probs and not rewinding tape completely. In fact the C7 which auto rewound after a tape was finished could sit there with the capstan motor straing all night trying to get back to the start of the tape as the sequence only stops when the machine senses the metal leader at the start of a beta tape.cheer Noel

Deepblues,

The C5 on which that machine is mechanically based suffers from issues with the drive belts aging. As well as this if you manually operate solenoids you can get the mechanicals out of sync with the machines electronic logic steps.

I would suggest that you get a belt kit and change the belts. You have to remove the base and flip out the base board to change the capstan and load gear drive belts. The others are changed from the top. It is not a simple exercise. Better to get some expert help if you can.

cheers Noel

Lord of the Betamax,

Sir, how dare you suggest I'm some sort of TV nerd! Actually, you're most probably right. I'm afraid I did enjoy the site you plugged, and some of its links as well!

Thanks, Bill.

Hi guys, I have a Sony SL-T7ME i aquired from a friend to help run my Sony Trinicon Video Camera mentioned in an early post. The unit switches on and lights up ok but the tape mechanism is not loading the tape in. Also if I press the buttons on the front they click and light up but nothing happens, it seems that if I manually push what looks like a magnetic switch in the back of the unit, with the lid off, then I can get it to temporarily fast forward and rewind, but not play. I can only repeat this if I turn the unit off and back on again. I checked the belts and all seem to be ok, hence FF and RW, anyone any ideas what could be wrong? Im not new to electronics but new to looking inside these Betamax units. Would love to get this working again, reminds me of my youth, cheers, Sean (deepblues)

I own a Sony EDV 9500 and have over 200 master tapes in std beta and ED beta format. My machine is in need of a idler motor assembly, I have not had any service on this machine for years. Does anyone know where I can purchase this motor assembly? I love the postings and I love beta. Thanks for what you all do.
