I have an SL-HF300 Betamax in pristine condition that has been in proper storage since 1987. I have the manual as well. I would like to sell it. I am hoping someone in the Bay Area would like it as shipping costs are expensive. It was hardly used prior to being stored. I would like $300.
Hi, I live in Livermore, Ca and have two beta machines, and about 800 tapes. Tapes are free and would sell both machines for $100. They worked great last time I used them (been several years). Would like them to go together, family said I have two weeks to find them a good home. Would need to live somewhat close, no way to ship it all. Text me please if you are interested. First come first serve.
The SL-700ME has a slow fast forward in it's design. There is nothing that can be fixed. I think the specification in the user manual states six minutes for fast-forward/rewind of a L-500 length tape.
I have a sony betamax sl-c7 where the 400v capacitors have been replaced (panasonic capacitors) and the 2sc2335 (were defective), the resistor and the known chip. now everything worked, but after 30 minutes, it was broken again, the 2sc2335 were broken again.
now i read that this happens more often, is there a solution for this?
Message for Simon
Sorry for the confusion.
thanks a lot for your reply and precious advice I wonder if you could help me to tell technical advice for improving the speed of ff on sl 700 mkII.
waiting for your reply in due time
Hi Mehrdad, I have owned several SL-700ME machines. The fast-forward is very slow, not much faster than picture search. This isn't a fault. It's the design of the machine. It's a very cheap latter day model. If you switch between PAL and NTSC, the motor speeds up slightly during fast-forward!
Hi everyone and best regards to palsite members
Actually let me right to my issue with my superbetamax in middle east is sl 700 mkii but in yours superbetamax sl s600
The main issue have at the moment the speed of ff is slower than Rewind due to i dont have SM i dont know the real voltage i test capstan the 5 pins except fg 4 pins the 2nd pin after b+ is 12vdc for REW is 9volt And FF is 6 volt !also I 've checked the whole sections of motor drive and capstan and servo section pls fo you have sm or face with this problem
Thanks in advance
I am in great need of a service manual for the GCS-1 Betamovie if anyone has one available. I�m in the US and it would need to be for the NTSC version, though I�m not sure any other standard existed�
Great that you got it going. I think you were lucky the loading ring slide and the capstan support rail were still in sync.
Sometimes that is an issue after taking out the load motor although the assembly is a little different in the SLF30.
I managed to fix the machine last night.
It seems as if the problem was that one of the gears on the bottom of the gearbox wasn't meshing with the gear below but was instead resting on top and the drive between the two was merely the friction between the surfaces. Looks like a manufacturing assembly error.
I attempted to lift the gearbox out but to look underneath but the cables prevented me doing so, so I refit it and there was a slight clunk as I reseated it and the gearbox dropped by a couple of millimetres. After full reassembly the ring assembly, and hence the tape load/unload worked perfectly.
I just repaired an SLF30 that exhibited the problem that it would not properly load the tape and would stop when the leading guide was about two inches from the end.
It turned out that the mounting post for that rear switch was slightly bent and by moving it to the left normal operation resumed. Strange if yours has the same issue.
The brake solenoid is under the rear edge of the reel motor assembly.
You can view if it is operating or not with the machine playing a tape while on its edge or upside down and the base circuit board, if there is one covering it lifted up (I don't remember exact layout) as you can see if the plunger tries to operate then drops out.
The solenoids have a momentary operate higher power winding then a hold winding which stays on once the magnetic circuit is closed. There is a fuse in the hold circuit which opens at excess temperature. Maybe it just fails with time also.
You can prove this out using a multimeter on ohms range to see if there is resistance to the ground or common connection from both windings.
I can email some circuit diagram pictures if necessary. You can contact me through my betaheaven.com website.

Machine fails to load or unload tape as a lever at the left-rear of the tape bay (as seen from the front) fails to actuate.
The machine was working OK other than intermittently slow fast-forward/rewind. After playing a tape the rewind went slow but finished but then the tape wouldn't unload with the unload motor gear spinning but the tape not unwinding from the capstan. Manually shifting the lever allowed the tape to unload. Similarly, if I load a tape manually moving the lever allows it to load.
The technical page on this site says "brake solenoid" but as there are no details about where it is or how to reach it that's useless information.
Does anyone have a service manual or knowledge to help with the repair?
A word for all VCR fans.
Machines do NOT like to be stored for excessive periods of time as many have belt's inside.
They should be powered up every few months and even allowed to play the odd tape.This keeps the mechanics in good order.I see so many posts now about ,'how they worked when being stored and then after many many years they now don't'.
Also in regards to the power supplies.If not being used for long periods it's better to unplug them as this saves the capacitors from over heating/drying out,especially as some like to use them in closed spaces with not enough air circulating around this vital area.
Also keep the machines away from cold environments like loft's and sheds as then you have the added issue of rust forming on vital areas.Same with the tapes this time mold will form and in sever cases ruin your precious treasured memories.Sadly far too many have not adhered to this. Expecting miracles from those who are having to turn away very contaminated cassettes.
Andrew this model use the same motor for load-unload the tape and as capstan
I bought years ago by internet a Sony SL-C7 I repaired the power supply but when I entered a tape didn't load and I listened a noise
I touch the load-unload motor and load the tape
When I played the image was unstable
I couldn't find a schema of this motor, I opened but I don't know what problem has
Perhaps one coil don't run, I have guarded this vcr
Got a collection of 3 Sony C7 's and the most recent one I have got out again. It's been storing for 8 years since it's last use and it was working whenit was stored.
Last week I powered it on. It was sounding sluggish but laced a tape which I then began to rewind and it snapped the tape. It would then just spin the tape constantly having been snapped. So it didn't lace and unlace properly. I ordered some used Betamax tapes and just tried one and now it does even less. It will let me put a tape in then when I put a tape in it just keeps making a noise and doing nothing with the tape. It will then eject when I press eject. Can anyone help please? Want to decide early as possible if it's an easy fix if it's just seized perhaps? or if it's a goner we don't want to waste time and money if it might just be worth getting another refurbished for the things we want to use it for. Many thanks for any subsequent help.
Martin has kindly added the information and template for the replacement of the Sanyo VTC6500 membrane to Palsite machine information at https://www.palsite.com/6500tech.html
Hello David my email is infomarbella at the Google mail. Encantado de conocerte
I doubt that you can obtain a new membrane for the Sanyo VTC6500 machine. My solution was to make a replacement.
I did that by creating a colour replica on sticky backed paper and covered the top surface of the paper with clear contact book covering material with also has a sticky back.
I can email you the picture to print if you contact me through my website Betaheaven.com

ivan I didn't find info about these vcrs
But I found in Ebay for sale, are NTSC and this site is for PAL
I waited to found service manuals in the web https://elektrotanya.com or in the web https://freeservicemanuals.info
These vcrs seems rare
