Very nice, thank you. I have a Superscope CD-312 that needs new belts too, looks identical to this Marantz 1810 deck. I have noticed that the internal workings of these decks are used in many models. Makes repairing mine a lot easyer.
I enjoyed this video. I had Marantz receiver back in the mid to late 70's. I had given it to my sister years ago, and I think he is still using it today. Marantz made high quality audio equipment.
Would you know if most Marantz cassette decks from the late 70s use the same motor? I have a 5030 3-head with a bad motor and I'm looking to cannibalize another Marantz deck to get the machine going. Thanks for any advice!
Thank you for the video. I have a Marantz 5000 cassette deck which is very similar to the 1810. I have two questions I hope you can help me with. The first is I changed the belts and idler tires and afterwords when I press the rewind switch it does not auto stop or pop back up when the tape has reached the end. The auto stop/pop up feature works for play and ff. Second question is do you know what is the replacement bulb for the record light? Any/all guidance is appreciated
Thank you Dave, very helpful tips here. I just wanted to ask you a question. I have a Marantz model 5200 tape deck. The vu meters don't work. No motion at all. I appreciate any suggestions if it's possible for you. Thank you.
@@12voltvids I was mistaken about the vu meters. They are working on output channel but the output channel on the tape deck doesn't have sound when connected to receiver, yet it works fine through headphones, and input recorder. The tape deck is equipped with another external adaptor output RAC connector channel which they work fine, in that case the Vu meters do not work. Now, I am hoping that you have some tips with the main output RCA connections problem. If you don't mind me to ask, What do you think the problem is? Your kind advice will be truly appreciated. Thank you
I just ordered a replacement belt set for a Sony TC-55 and at over 17 bucks plus shipping it sure makes it hard on the wallet to keep this great old equipment in top shape. Belts are SOOOO expensive for what you get.
Considering that I used to buy a 10 pack for 2.99! Yes they are. The tiny dime size belt for my Teac DA40 cost me 20.00 US by the time the shipping was added.
ZenithClarity1969 they must know that it's the most common problem in these cassette decks and players so they raise the markup so high. I recently ordered a belt from ebay for my beautiful Sony Walkman F2, for $4.90, I don't know what it costs with shipping so maybe $6. Not too bad
I just got into fixing with cassettes, and when he mentioned rubber bands I busted out laughing because I tried that my first time. But I'm expecting some belts to come in tonight so hopefully I can finish my first project.
I have a Marantz 1810 cassette player, the cassette player works, the needles dont move, and the lights come on, but there's no sound coming from the speakers. Any advice on how to fix it
Nice tip for the sizing of the belts when they're destroyed. I have an Akai GXC-725D cassette deck that looks very similar to this unit. It's got the "Glass and X'Tal Ferrite Head" printed on the cassette door. It plays fine but doesn't record. I'm not familiar with how the record mechanism works in cassette decks. Would you be able to go over the general idea of how to check for record problems? I think it might make for a good video. Thanks in advance for any help or tips you could impart.
The GX heads were exclusive to Akai. My GX265D reel to reel has 6 of them. That is 2 erase, 2 record and 2 playback.Obviously this is an auto reverse deck, and it has a center capstan with direct drive reel motors. To reverse a switch changed the heads, and the ac motor reverses direction.
I am working on a 50 year old Star Roamer tube radio; it has a power transformer, which should provide isolation; still has two wire power cord. When plugged in one way, 65 volts ac on chassis; when plug is reversed, 27 volts ac on chassis. Can this be caused by leakage from old power transformer? Thanks for your opinion. Will replace power cord with modern grounded, three wire cord, of course.
just been watching your video im sure here in Britain that Marantz tape unit i had the identicle machine that also had switching problems but it was badged up as Sharps.
I have the 5010 looks just like yours it was about 200 dollars i just had a service center put new belts in last year today my take up reel lost most of its tork i dont use it mutch thanks so i put it in the closet until i can get it fixed they dont make that good quality anymore
Is it just me but towards the end after the fix and youre playing the tape originally the spools seem to turn smoothly but then when you see them again they are jumpy? Maybe thats just an illusion due to recording/digitizing/uploading/yourtube reencoding?
I'll do that when I get the correct size belt. After visits to 3 shops I could not get the exact size, and the one I did pick up is too tight. Since the owner is going away for 6 months he didn't want to leave it, so I put the belts in for a demo only, and then removed them until it comes back to get the correct ones installed in the spring.
Typo, the 9 is next to the 0. I didn't catch it in time on the title, and since my internet bandwidth is metered, I have no plans to re-upload it to fix, as the source file is about 4 gigs.
what do you use to clean the gummy gunk off the pulleys from the belts? I have a 1810 deck that I got for free and how much do the belts go for? awesome vid! very helpful!
Good Gawd. A rubber band. Well it wouldn't be the first time I've seen that. How on earth people expect it to run for any time, let alone steadily enough, is quite beyond me !
I see this all the time.Stability is actually very good as the flywheel effect of the capstan shaft smooths out the elasticity effect, but they won't last long. The problem is finding belts. I had to go to 3 different shops to find the belts for this one, and it isn't getting any easier. that's for sure. Nobody wants to bring in any belts, and even getting stuff of the internet has become a crap shoot with all the sub standard parts out there.I ordered some belts off ebay, and they were pulls from another tape deck that were looser than the original ones I was replacing.A rubber band is a fast band aid that will get the tape deck up and running again in a pinch, but it won't last very long.
Good old tapedeck, nice fix :-D It allways supprised me that the dc motors on old tapedecks last so long, ive seen a lot that look like that one, most still work :-D. Ok the speed and wobble isnt superb after all that time, but most people play pop music so its not really noticable. Ive seen a lot of belts become black sticky goo, but thats mostly on phillips equipment. The mode switch is a bugger for playing up, when spray cleaning wont work ive dissasembled the switch and cleaned the contacts with soaked paper. There is allways a black coating over every contact, all the manufacturers must have used the same lube in those days.
I have also disassembled switches and found black gunk in them. Many times that is from someone trying to clean it with the wrong cleaner that leaves a residue behind. Sometimes it was blue gunk, and other times green.Tuner spray was the worst. The old NuTrol which was FreonTF with a lubricant was the best, but you can't get that anymore due to FreonTF being banned due to it eating the ozone. The new NuTrol is relatively good, but is now diesel based (diesel is a good solvent and lubricant) Probably has some other solvents in it too, but you can sure smell the diesel, and it makes a nice flame thrower.
Blue or Green gunk, ive never seen that before lol. I used to use a switch cleaner called servisol, and it worked well on most switches/pots, but those pesky tape record/play mode selectors didnt allways play the game. So it was dissasemble and clean with metholated sprit and paper, and for stubborn contacts i had a odd rubberish block from maplin electronics that had fine abrasive in it, handy :-D. Keep the flame thrower away from that tape deck :).
Cramolin Red and Blue is what we used before Chlorofluorocarbons, specifically Dichlorodifluoromethane were outlawed. That stuff really worked. One was used first, to clean corrosion, chase dirt and noise, the other used last, was to preserve it when done, DeOxit D5 & D100 is what they replaced it with, which like Nutrol are OK but nowhere near as good as genuine Cramoiln was. Oddly enough you can still buy old school Freon if you have a license, which I do. It is now cheaper by far than the new non-CFC refrigerant, the opposite of 20 years ago. I charge my '81 Corvette every so many years, 5 or more, when it needs topping off, The old stuff cools off much better than whats used today, which is why I never changed the car over. Overall, it was better all the way round to stay with the old stuff that lasts years between fills. At 5$ a 12oz can I'm not arguing the logic !
Oh and I use rubber bands as belts all the time... Those bands from bracelet making for kids... but I onky used them for eject mechanisms on pc dvd drives becsuse that is almost always the problem and they are accessible from the outside and i had thousands of these damn things lol!. In any other scenario I would source the proper belts tho.
Bloody elastic bands to fix a Marantz. Shit, whatever next? But it has caused much laughter here in Suffolk. Keep up the good vids. Warm regards Wayne and Nina.
It wasn't so much the added cost of replacing the light. I didn't have one in stock, and he was really pressed for time. The owner was heading out of the country for 6 months to go to Mexico for the winter, so he couldn't wait for me to get into the parts stop to get one. I only have every 2nd Saturday off, when I can go parts shopping as the parts shop isn't open Sunday or Monday and even ordering one off the net would have resulted in a delay. He wanted it back quickly and said the light didn't matter because it sits in a cabinet with a solid door so he doesn't see it anyway.
These ones cost enough. Yes I know what things cost. I wanted a pinch roller for my reel to reel and found a supplier that wanted about 150.00 for one. I want to fix it, but not that bad. The old one all cracked and dry still works.
yeah that is a lot maybe you can find a parts unit and take it off of that one. i have ordered some belts off of ebay from china i just got them today so i don't know how good they are yet. i have a few boomboxes and tape decks that need new belts. it was only $4 for 100 belts
Yes I have some. That works for pinch rollers. I did a video where I restored the pinch roller for my open reel Akai as etting a replacement pinch roller was 140.00 US, so I tried rubber renew and it worked fairly well. That stuff stinks like wintergreen,
I get you the guy who used rubber bands got hundreds of hours of free music. Rubber bands clean off Easter than than gummed up belts i am going get some rubber bands and experement. If I get same level of wow and clutter i will never buy a £20 belt kit again

Thanks my Marantz 1810 turned out awesome. 👍
Technicians like you are long gone... at least in my area.
Would you know if most Marantz cassette decks from the late 70s use the same motor? I have a 5030 3-head with a bad motor and I'm looking to cannibalize another Marantz deck to get the machine going. Thanks for any advice!
Motors probably the same

I got an old reel to reel deck with an analog counter. What do I need to make a digital counter for it ?

I have a Marantz 1810 cassette player, the cassette player works, the needles dont move, and the lights come on, but there's no sound coming from the speakers. Any advice on how to fix it
Check regulators for amplifiers.
@@12voltvids Thank you I'll do it and I'll give you an update
what is the name of the song with which you do the final sound test please.
I noticed most tapedecks and cd players dont have a line fuse so i put one in i have many videos doing that is it a good idea
Can you give the address where you got your belts from. thank you
I can do better I can give you the website Amazon.
4:20 What is the name of the cleaner? Neutral? Neutrale?
Fake Name
NUTROL. yes that is how it is spelled.

I have the marantz 5010 i paid 180 dollars for it i just had belts replaced works great bought it in 1980
How did you find belts?

I am working on a 50 year old Star Roamer tube radio; it has a power transformer, which should provide isolation; still has two wire power cord. When plugged in one way, 65 volts ac on chassis; when plug is reversed, 27 volts ac on chassis. Can this be caused by leakage from old power transformer? Thanks for your opinion. Will replace power cord with modern grounded, three wire cord, of course.
I'd be inclined to look for leaky caps, starting with any filter caps, whilst also looking for any obvious signs of a short
More than likely a leaky chassis isolation capacitor that goes from the line cord to the chassis.
Can anyone tell me how to remove the lower screw of the fly wheel? i can’t unscrew it because the screw is hardly accessible?!

It's probably an illusion, it happens to me all the time on my tape decks, it scares me for a second that it going to eat my tape lol.
Isn't necessary to do a speed test on this unit after re-belting? With the 440 hz test tape and guitar tuner.
I'll do that when I get the correct size belt. After visits to 3 shops I could not get the exact size, and the one I did pick up is too tight. Since the owner is going away for 6 months he didn't want to leave it, so I put the belts in for a demo only, and then removed them until it comes back to get the correct ones installed in the spring.
