Way back in the '60s, when I was a computer operator (IBM 360) we cleaned the heads - often - of the tape decks, no gloves. We got strange, white fingers - very little health and safety back then, and the fluid had a peculiar smell too. Mind you, it did remove the ink from our fingers which we got from the 1403 impact printer ribbons.

I think you will find that the motor is fixed speed. The switch is only for equalisation. Open reel tapes use a different equalisation for 7 1/2 verse 3 3/4 These Akai's had a physical adaptor that screwed over the capstan of the open reel part to adjust the speed . The speed of a compact cassette is 1.875 inches per second. That's how this system can work. The motor is fixed speed. The speed is adjusted by adding or removing the adaptor on the capstan and then the equalisation is set by the switch. The poor quality of the cassette sounds more like the heads need a good clean or are worn. You may also find the unit could need recapping and possibly other components have drifted, contributing to the poor quality. When new these units actually had quite good sound quality and quite high quality recording ability.

Dead on! The cassette deck SHOULD only record at the one speed as the tapes would be totally useless for playing in any other machine. That speed, with the one exception being secretarial dictating machines that ran slower, was and still is the industry standard. TEAC reel-to-reels favored a switchable speed control rather than the capstan adapter AKAI used. I liked the TEAC recorders better just for that reason. No chance of misplacing that adapter and rendering useless a lot of tapes.

Great job on that Akai. I grew up with these. Robust, and made to last unlike the crap we get today. Real metal, serviceable. These are meant to be kept and enjoyed. Saburo Akai would be proud of you. Akai had a wonderful reputation in cassettes and reel to reel. The GX heads were meant to last forever. Even had one that had 8 track and Cassette and Reel to Reel. But the heavyweights the GX747 and so on are the crem a la crem of Akai reel to reels most know. Though the Pro 1000 reel to reel is to die for.

I've never seen a reel to reel with a cassette player, but I used to have a reel to reel with an 8-track player built in.

Wow, that was nice to watch. I bought mine in Japan around 1976 when i was still working as a merchant marine. I have both the GX1900 and the GX1900D. I had them cleaned a few yrs ago and still run like i just bought them. I also have the Akai GX630DB reel to reel recorder (without casette recorder) which i use the most, less mechanics inside.

in the seventies AKAI came up with a feature they called 'glass-ferrite' heads. These are tapeheads that are covered with a thin layer of hardened glass where the tape is sliding on. They claimed that the magnetic field is focused to the distance defined by the glass coating. These tapeheads are really not wearing out. (due to this they disappeared silently from the market - you can't sell a product that is not dyin at all) These machines often only suffer from oiling issues and dust on resistor surfaces. Japanese reel to reel tapemachines were also called 'oiltankers' because their manufacturers often used industrial grade mineral lubricant that produced a typical mineral oil smell and hardened out over the years. These AKAI's are reliable like tanks.

Good job, you approached the problem better than many other professional mechanics. All my audio equipment (AKAI/Pioneer) is from the early 80's, great, some quality, almost no problems after all these years. As for the residual foam behind the Vu meter, the meters are held in place to absorb shocks from transport. This also makes the meters last longer.

The stuff on your reel to reel tape heads and tape path are a result of Sticky-shed syndrome from someone running a deteriorated tape thru the machine. What many don't know is if the unit is not cleaned after running a bad tape thru it, the bad tape can destroy every tape that is used after as it transfers the deteriorated oxides to the next tape used and so on...

Tape from the late 70's into the early 90's, all brands, all types, audio and video, had issues with the binder that adheres the magnetic oxide to the tape base. Some professional studio master tapes have deteriorated so badly, they are unplayable. You can "bake" the tapes at low heat to revive some of them enough to make a copy.. Just look up sticky shed syndrome in a Google search. Some pre sticky shed era have an issue with the lubricant in the oxide drying out.

I used to have an akai X-1800-SD, it was a reel to reel recorded with a built in 8 track recorder on the side. What was interesting was the fact that the 8 track player’s capstan was the same as the reel to reel’s, so when the speed of the reel to reel was changed it also changed the speed of the 8 track as well.

Nice job. I've lost count of the number of 'dead' akai machines I see advertised by sellers who clearly don't even try lifting the shutoff lever. I think it's obviously a generations thing. I grew up with these kind of recorders so it's difficult for me to grasp how someone can't understand how to use it. But what's common knowledge to me is alien to most people 30 years my junior, and no doubt vice versa.

That's a cool machine and you did great at repairing it.

You've gotta live in the Tampa Bay area: I saw one for sale recently and dithered as I have a room of broken equipment. Naturally, I regret dithering!

As far back as the middle 60's I have always had a reel-to-reel recorder of various types. Compared to the Chinesium JUNK being sold up until recently, these old reel-to-reels were built like a tank! They were very solid and built to last. Even today I still have two identical TEAC reel-to-reel recorders in my system. The only thing I have had to do to either of them was to replace the drive belts. While I prefer TEAC's, AKAI's were really good. The Roberts recorders often seen are just rebadged versions of AKAI's. There are still a lot of pre-recorded tapes on the market today. The biggest thing to look for are the ones that have been redubbed from originals due to tape age or damage. If the equipment operator was really good at it, copies are not all that bad but often I've found redubbed tapes that had so much noise that they could be irritating. The only reason I would redub a tape would be damage on the original such as substrate deterioration or edge rippling caused by badly aligned equipment or having been exposed to heat. In cases like that you really have no choice if you want to preserve the sound. The drawback to tape now is the same thing that has hit the CD/DVD market, lack of blank recording medium. With the outrageous explosion of streaming audio/video the manufacturing market is fast disappearing.

I have an Akai X-355D which is older than yours, I was told it was their first solid state deck. It's a 3 motor deck with solenoid controls, a built in power amp with 2 speakers (the speakers are just speakers but the amp puts out really clean sound). It weighs 80 pounds and came with an optional wired remote control. It also had a new Akai innovation - crossfield heads! This boosted the upper frequency response to beyond 20,000 hz. I had a later Teac deck but the Akai had better sound. Once smaller gap heads were developed Akai abandoned crossfield heads but licensed it to Tandberg who continued to at least the early 80s with it. This deck also has track to track dubbing and a bunch of other special effects I never use. It does it by lowering or raising the recording head and playback heads relative to each other. There was also an available 15 inch reel kit but I don't have it.

My first tape recorder was a Grundig with half big reels. Only later when working in a studio we only used Revox. B77 and most of them A700. I still have a A700.

This is a mostly great repair video. A few points though... 1 - JIS stands for Japanese Industrial Standards. So, if it's Japanese and made any time in the late 50's onwards, it has JIS screws, even if there is no dot. And, even if someone has already been in there with a pozi or a crosshead driver and chewed them up a bit, a JIS driver will still mostly fit and work. Buy a set for 10 bucks and use them. 2 - Sewing machine oil is a good shout. Far too much of it though, and when you use too much oil, it will eventually make it's way onto things that do not need oil! Use a cocktail stick as a dropper to apply a tenth of the oil sprayed on some parts here. Also, the grey stuff on the mechanism plates? Clean that off with IPA and use a very small thin film of Molybdenum grease because the original stuff will have dried out and will cause sticking. As for the beige (once white) goo on the spindles, a light lithium gear grease is good. Just don't use too much. 3 - You stripped and rebuilt the whole cassette mechanism but didn't replace the pinch roller? Ytho? 4 - Obvious trolling (34:44) with Sony reels on an Akai!😁

Personally I prefer to use teflon based oil. This is very thin oil, excellent for clocks and watches, that doesn't thicken over time. You can also use silicon grease. Remember to always clean the capstan after remounting it because as it passes through the bearing it gets greased, so a good alcohol clean afterwards avoids grease on your tape. Rubber surfaces can also be cleaned with alcohol.

I admire your patience

wow! what a deal! i had a radio shak reel-to-reel back then and i paid $50 used. i did sound on sound recordings. i also taped music shows off my stereo.

To service this unit you have to order two separate belt kits. The reel to reel kit is the same as the standard model and the belt kit to the cassette is the same as the separate cassette deck they sell. I do not remember the model numbers anymore that you need to order as I haven't seen one in for service in many years. They also made a model with an 8-frack recorder in the right side of the deck. The model you have is from the seventies and may have had the belts replaced by now.

These machines are so much fun. A few weeks ago my boss gave me an Akai 4000DS, which I've already been using for recording drums, and a Pioneer RT1011L that I haven't even plugged in yet.

Be careful with all that oil, one little drop on a rubber part and it wont grip ever again. have ruined many capstan wheels by excessively oiling them. That's one of the reasons why using grease is better in cases like this because thin oil can fling out in operation. and the other would be that oil isn't made for a lot of load, for example the piano key mechanism would need grease, having only oil on the surfaces will scuff them up after some time

The Techmoan grade quirky unit, indeed.

Almost all the screws seem to be posidrive rather than phillips. Phillips screwdrivers make a mess of pz screws. I think they are much more common outside the US. Interesting video it's such a shame this sort of mechanical engineering is dying out.

I'm thinking the cassette deck can record and play back at 3.75 ips and not 7.5. It sounds exactly an octave lower on the Sony cassette deck. A cassette is 1.875 ips normally but some decks gave you the option of a higher speed for better quality but sacrificing time and would only be good on decks with that extra speed. That being said, I'm thinking the cassette deck may have needed demagnetized, the bias was incorrect, or both. If it was made in the 1970s, the older stereo decks didn't have that great of a frequency response like they were able to achieve in the '80s and '90s with the HX Pro feature on some decks. Mechanically, it looked like it was very well made, it just needed cleaned up and you did an incredible job on the whole thing. Very cool!!!

@@HifiJelly, this can also happen if the brake pads are really worn. The brakes can't grip the turntable hard enough to stop the reel from turning. Replacing them can be hard to do unless you have a source of felt sheeting that has an adhesive backing and are really good at cutting it so the edges match the original. Sometimes you can strike gold on eBay and find a source of the parts but most sellers know what they have and the prices can be hefty. I bought a TEAC on eBay and the GORILLAS in the USPS managed to bend the shafts on both turntables even though the recorder was packed really well. I was lucky enough to find a pair of NOS turntables from a closed repair shop that were still in the factory wrappings. I replaced the damaged ones and the recorder still plays like new. I did save the old ones just so I would have these felt braking pads. On SOME recorders, usually the cheaper built ones, they utilized an external felt lined strap that would grip the outside of the turntable base and stop the turntable from spinning. While much easier to fix the quality of the recorder could be questionable.

I have a couple of these. I've never tried to turn them on, but they probably work. Nice rework! Did you find a service manual?

That is really interesting that the cassette deck speed is tied to the reel-to-reel speed. Your only option for any dubbing would be 3 3/4 IPS on the reel-to-reel, in either direction. I wonder if the reason your test cassette was especially hissy was because the cassette deck isn't calibrated to play or record tapes at high speed. It would be interesting to know if you get better results with a 3 3/4 IPS source (and therefore recording at the proper 1 7/8 IPS cassette speed).

@@andrew1479 I've never heard of using toothpaste before. Does it have to be a specific kind? I've got an 8 Track player with a really worn and corroded head, I wonder if toothpaste might help that.
