Thanks for posting this stuff it’s very informative and I have picked up many tips on fixing my reels and getting them back to working condition because they’re the best and coolest items from way back in our days. Lol 👍👍
Greetings: MG Chemicals (Canada) makes Rubber Renue. Originally their formula is as listed in this video. Item 408A. California Air Resources Board requires 408A to be diluted by 25% using iPA before use. They had a product that was compliant, item 408B, which has been discontinued and replaced with Rubber Renue 408C that does not require dilution. Soaking pinch rollers until the Rubber expands will allow most contaminants to be able to be washed away prior to allowing the rubber to evaporate all of the applied chemicals (the longer the better). Without soaking, only the outer surface will be treated.
The company that makes this item which is MG Chemicals states specifically that it should not be used on a pinch roller. This information is not printed on the bottle. But, after several phone conversations with company personnel I found out that since it contains oil.... it is detrimental to use it on a part that comes in contact with audio or video tape. It does a great job in giving new life to rubber components, but, can cause trouble if used on the pinch roller.
American Recorder Technologies S-721H-4 Cleaner Fluid is apparently what's recommended for tape heads, capstans and pinch rollers. It's 98% Hexane and 2% Cyclohexane. Highly flammable. Not sure if it swells rubber, though. It isn't cheap at 29.99 for a 4 oz. bottle. It's available on Amazon.
This is a kind of special pinchroller made of two different rubber type. The outside rubber is different from the rubber that will go in contact with the tape. You can see this by yourself just watching closer to the pinchroller. That pinchroller are gone, nothing can fix it. Anyway thankyou for sharing this interesting video.
MVVblog Well when I started this one was so bad that tape slipped. Now it plays fine. I don't use this tape deck anyway as the head is worn quite badly. I have 2 other reel to reel decks that I use for open reel tapes. This old 1710 is a 2 head and my other decks 3 head and 6 head. The only thing this deck has going for it is the tube amplifier and Built in speakers.
"Keep container tightly closed" is the ultimate safety precaution. "Your honor, my client was instantly killed when he used the substance that the defendant makes available". "Your client either didn't read, or ignored the safety precautions by opening the bottle. Case dismissed!"
Those are beautiful machine's.. I'm looking forward to the fix on the second machine.. I like the way the VU meters light up.. Love your vids man keep up the good work. Shout out from Nova Scotia.
I always worry about chemical treatments, such as this one, because there's no way to know if the chemical will continue to have a slow and long lasting chemical reaction that will continue to deteriorate the material in the following months or years. This would not worry me too much for a pinch roller that is in such bad shape as the one you rejuvenated, but I would worry about using this on a pinch roller that is in much better shape, such as the other one that you treated. I saved some old pinch roller on my mini lathe. What I basically used the mini lathe to remove the top film of dried up rubber and exposed the fresh rubber that was still underneath. The pinch rollers I saved did not have any cracks in the rubber, though. They looked good, but they were slippery. After I shaved off the top film on the lathe I made them much better. I didn't even have to reduce the diameter for half a millimeter. The capstan diameter must be exact, but I think pinch rollers have more of a tolerance, so if the are just a hair smaller in diameter it makes no difference. Anyway, those pinch rollers I shaved still work great and they don't put any tension on the tape, such as pulling it off the straight path (which was the case before my treatment). In any case, thanks for sharing your videos.
This stuff transfers its solvents to the tape which will eventually stick together on the reel. If you want to use the player to say digitise a tape and then throw it away there is I suppose a justification in using it, but never use this for archive tapes that will be used again - never!
A close friend who was an experienced electronics repairman ( Actually, he could fix about anything electrical, mechanical, pneumatic, hydraulic and whatnot, a true high priest of the Machine God) always jokingly insisted that only cleaners, lubricants, solvents, etc. that definitely caused cancer, birth defects and laid waste to the world around us were the only ones that actually worked. When I saw the title of the video, I remembered a bottle at the shop that was labeled Video Renew and wondered if this was maybe the same thing.
Oh you mean carbon tetrachloride, xylene, and all those nasty ones from back in the 50s and 60s. Freon tf was good but it eats the ozone. I know many an old tec, correction knew many but they all died of cancer. The engineer that taught me the fingernail had clean trick for when you're on the air and you don't have time to unload the tape and clean the heads thread the tape and cue it back up again, he used to clean heads with a cloth soaked in xylene. We were all told to use that on video and audio heads and 99% ipa on rubber parts. (Xylene will make rubber soft and is one of the ingredients of rubber renew) even the guys that did not service equipment but just were in the supplies business where they had cans and bottles of all these chemicals that they were shipping out to the repair shops got exposure just through bottles being broken leakage etc they're all dead and they all died of cancer. Two suppliers that we used to use when I was in the business the owners both developed cancer I think it's a pretty good call that it was due to the older chemicals because they were in the business of supplying supplies and parts for many years so they had dealt with the old stuff and you get leakage and spills and so forth a lot of these chemicals came in glass bottles so if you dropped it it would break and then you'd have a big exposure in your shop. they banned most of these chemicals for a good reason because people were dropping dead after using them for years.
@@12voltvids Yeah, I worked for 25 years or so in the screen printing industry, early on, back in the late 1970s there were some horrific solvents in common use and to some extent, a lot of the chemicals used in the newer UV cure inks ( The older stuff was solvent based inks.) like monomers that get polymerized by catalysts and intense UV light from paste like ink into suddenly solid printed colors ain't all that great for you either. How bright are the UV cure light sources? Imagine an electric welding arc light over four feet long. The prints went under the light for only a couple of seconds and the lights were usually (Usually) well shielded but there was always a little leakage here and there. Not the healthiest environments. The places I worked printed some big stuff (Banners up to 10 feet x 3 feet, 4 colors, one after another on the same press with 4 print and 4 UV cure units) and smaller items as well. I retired in 2020.
Yes it is good stuff. Stinks though, use it under well ventilation. I now have 3 Akai reel to reel machines,and I have used it on all 3, and they all work great now.
I had a unit i for service with his rollers and the w/f was amusing it was so bad. Customer had to send them back to be redone again and pay postage both ways and broker fees a second time. Was a very expensive lesson.
Every thing we use causes Cancer, as every thing one uses has all kinds of Precautions on the label Seems every thing we use is bad in one way or another, Same thing goes even for the most harmless stuff, just depends on how it is used or where it's from. Seems we all take risk every day with what we use,.. Follow all directions but this surprises me that this stuff has so many precautions, just where can one use that safely,.. but hope all goes well and it works..
Exactly! The dose makes the poison. The vast majority of people cannot evaluate risk. In the day used to get patients who did not want a single x-ray as they were pregnant, but were smoking 20 fags a day.

here I give you three hundred likes, but as I see it, you already had problems with the barber shop in 2015 and this time is not a pandemic situation :) :) However good work.
Hello great video I have a teac a-4010-sl and when I play or record a tape as the tape gets to a quarter to half way through to direction goes into reverse on it's own clydesight told me to contact you he said you would know and be able to tell me step by step what to do and what part should be chanda he gave you great praises be well and safe
14:25 - that was painful to watch. The wow & flutter is off the charts with that chunky roller. Search "Terry's Roller" to get a new tire for that pinch roller hub, the music will sound a lot less like the singer if gargling salt water. 🙂
Cost to have that roller done is over 175.00 by the time shipping and taxes fees ect added. Not putting money into an old piece of equipment that will never be used the cams are ready to fall apart. I actually do have a few rollers that will fit this but then again why? The head us so worn you can break your fingernail on it. It's worn out so no money going into it. I have had this since 1969 and it has been well used.
@@12voltvids You got your money's worth. To be clear, almost all of Terry's rebuilds are $50 + $10 shipping. But I agree with you, in this case it isn't even worth that, unless it was being prepped for a collection or something odd like that. Enjoy!
@@ray_notes8170 I had s quote years ago and by the time shipping was added and he refused to ship by post only fedex 50usd will have 42 in broker fees added. It wasn't no 50 either at the time he quoted me I believe it was 80 or so for one I enquired about. This was for an old ferrograph that I have.
@@12voltvids yeah. That's not cheap. I'm replacing the pinch roller on an Otari MX5050 8SHD 8-track reel to reel; well worth the price. But my situation is a bit different since Terry only lives a couple miles from me, so I dropped off the old wheel personally. Online they go for $160. For my 4-track, I just bought the tire for $15. I'll see if I can repair it myself. Love your videos by the way. I've watched a ton of them.
@@12voltvids Not sure. I'm asking. I've read where the capstan governs the speed of the tape across the heads. If the pinch roller is slipping, would that not affect the speed?
Hello, I have an Akai GX286 in which the roller is not cracked, but its consistency does not look like rubber, but rather bakelite, will that product make it come out with some spongy consistency? I would also like to know if the roller of some other Akai fits this model? Sorry for my poor English, I am using the google translator. Greetings Marcelo.
+365 GTA MUST PLAY 247 They are just generic rubber reel clamps. We're popular in the day. Rare as hens teeth these days. Clothes pins work good too. More modern machine had locking hubs.
Many Akai use the same roller. I have 2 other Akai, GX265 and 4000DS and they both use the same roller. The 4000DS is almost the same machine as this, but solid state, and a 3 head model.
+Gary Farris It's all tubes. No transistors. Tube preamp, tube power amp, tube record amp, and bias oscillator.this old unit sounds very good, except that the head is wearing. I use my GX265 more as it has the glass heads that just don't wear out. Akai claimed that you could run a tape over it 24 hours a day for 20 years.
Wow! thx for the info. Never knew they made tube reel to reels. I would assume its recording capabilities are outstanding, but do you experience microphonic noises and such in playback? I used to live near a 50,000 watt radio station and i could hear their broadcasts through my fender amp.
+Gary Farris All the old ones from the 60's were tube units.Haven't had too many problems with it. Had a tube go gassy once, had a cool blue glow in the tube, and it hissed like crazy until I changed it. I once had to work in a house that had a 50,000 watt AM station in the field out back (farm house) Everything in the house played music. Dish washer, toaster, water tank. You could feel the RF on everything metal. The entire house was buzzing with RF.
They never used to print these hazardous material warnings on things and then the nanny state, that would be California started finding that everything is known to the state of California to cause cancer.
Should I be worried if it does gets on my skin? Also can just by smelling it give me a one way ticket to the doctor? If so, I am surprised that this stuff is legal.
+ranzenottel I wish it was that easy. I have been searching for a replacement for my old Ferrograph I wish to restore for 6 months, and so far nothing.
A much better way to restore life into the pinch roller is mount it on a drill, and gently apply 1000 grit while it's turning. After again while turning with a drill apply min 90% isopropyl with a cutip and then apply this chemical.
I've tried that a couple of times and yes, it works (even just the drill part). Even a simple drill and a few minutes can do miracles with a rubber wheel.
+Donald Ellett Rubber renew does stink yes. Smalls like wintergreen. Same smell as Rub A535, you know the stuff you rub on your back and it gets warm. Same small.
You can buy a new tire for the roller for $19 and not worry about destroying tapes. Not sure if one of these would fit though. www.vintage-electronics.net/akaipinchrollertirepr1.aspx www.vintage-electronics.net/akaipinchrollertire.aspx
Yes I found his site too. 80 US. plus the shipping both ways. 80 US, ,plus 15 to get it there, and another 30 to get it back because US to canada shipping rates are criminal.
Barry Sheridan If you watch the Sony reel to reel I worked on a month or so ago. Those wobbly rollers were done at that shop and they had to be redone as they were "dancing!"
What a load of rubbish. Where's the sense of adventure? Not that poisonous at all. Over half the warnings apply to water and oxygen. That must be the first and last time Dave used that stuff with rubber gloves. People worry about such warnings disproportionately as most people cannot correctly or logically evaluate risk.
I used to use this stuff without gloves as did my coworker. He used it much more than me because he was the turntable guy. He got cancer. The guy that ran the supply shop died of cancer, my old bosses dad who was a tech died of cancer as did my boss at the first shop I worked at. I get nervous every time I cough these days as I was exposed to all those cleaners that were sprayed freely at every shop I worked at and we had no ventilation. I have had more people I know from the service business die relatively young from. Lung cancer pancreatic cancer bladder cancer liver cancer leukemia you name it. Pretty much every colleague I had in the business has been sick. Considering all the chemicals we used to use it doesn't surprise me. Carbon tetrachloride was a cleaner but thank god it was gone before I got into the business as all the older guys I knew from that era are all long gone now and many passed in their late 50s to early 60s. Coincidence? I think not, and now we get all these warnings on cleaners that were never there before. I try not to get anything on my hands stronger than isopropanol .
@@12voltvids I also wonder if the past use of solvents will catch up with me. In the Navy, the preferred cleaner was trichlorotrifluoroethane or CFC-113, is a chlorofluorocarbon. It has the formula Cl₂FC-CClF₂. This colorless, volatile liquid is a versatile solvent. It has attracted much attention for its role in the depletion of stratospheric ozone. If I recall, the only warning on it was do not drink.
@@bshingledecker yes I remember that. I'll have to look at the chemical name of the freon tf I still gave and see if it is the same. It may have been dichlordiflororthane. It also burned the ozone, and the warnings were not to smoke when using it as burning it made it toxic. I am concerned as well as for 20 years that stuff was sprayed every day to clean controls, heads ect. My old boss used to close the door to the service dept so that customers wouldn't walk into the back and disturb us so the fumes were trapped with us. The guy I worked with developed early onset alzheimers and I am sure is no longer with us. I haven't seen him in 15 years. He was my assistant and did much more tuner and control cleaning than me. I was working on vcrs so my cleaner of choice was isopropanol alcohol. Got that stuff on my hands all the time and nutrol. The stinky ones were used by my assistant.
Tape deck works. Better than spending 100 for a renewed one on a tape recorder that isn't going to see much use due to pot metal cams just waiting to crumble.
@@12voltvids Also instead of applying solution onto rubber make a tyre out of 12mm rubber sheet on lathe and stick it on to the metal rim of the pinch roller...
Do you honestly think that flicking buttons on and off makes you look competent? What is does is show how people break devices. Why on earth not remove the last couple of minutes from the upload?
This was to show that the unit was not functional and it will not damage anything. Of course if you were intelligent you would already know this. Activating switches will generally clean the contacts so if a fault was caused by an oxidized contact switching modes back and forth will clean the contacts by mechanical action. Everyone watching with even the slightest knowledge of how things work knows this already. When we clean controls and switches after spraying in cleaner the switch or contol is operated quickly from end to end to effectively clean it. But then you just proved to everyone that you know nothing about electronics by the comments you made.
It was more like 2 minutes, and I am just stressing the fact that this stuff is hazardous. Yes it did work as claimed and this reel to reel recorder works to this day.
your reflection off the brown bottle is how police forensics catch thieves in liquor stores ! From what I see you're 5'11 & 240 lbs. Around 50 yrs old, with a 43" waist.
