Thanks for posting this video! Just had one of these in to fix the perished belts...the gear was fine thankfully. Watching you disassemble the transport answered a lot of questions for me that an exploded diagram doesn't. The trick of putting the belts around the posts was especially helpful. Great work!
Well, if your prepaird to move to the rural North Sweden, you would find one customer who would pay. If the deck sounds good, it's worth reparing. Amongst all the players, I have a JVC TD-V711 im prepaird to take out a loan for the day it breaks.
Well done, it should last long enough to transfer the tapes :-D Back in the 70's the pulleys were brass and a grub screw locked it on to the shaft. Bomb proof old beasts :-D
@@G.M.C2005 it won't be as strong. The only way to do that would be to replace the part. Back when these were available they were pennies. We used to buy these parts from Sony. A bag of 5 was 1.00. same as we would buy bags of belts for walkman's. A bag of 10 was about 10.00 Today no parts available. A few are attempting to 3d print and ask 30 to 40 for one part. Not worth it. Even for your own machine.
@@RetroMechanic if your test with a capacitance meter (like i did with the fluke) and they measure really high then there is a good chance they are going electrically leaky. For example if you measure a 100 uf cap. Tolerance is +20 -10. So if it measures between 90 and 120uf then it is good. If for example it measures 82 however then it is likely dry (the ESR will be high) and on the other hand it measures 163, well there is a podsibility it is going electrically leaky. The only way to know for sure is a high voltage break down tester that will charge the cap at the voltage it is rated at and measure microscopic leakage in the microamp range.
10:37 that little demon... I carefully opened the central hole a little bit and added a superglue droplet on the crack. This kind of plastic shrinks over time and that's the reason this gear cracks. And yes, my deck became berserk before my repair. Wild speed changes, a very loud rasping noise, tape rewinding very fast and finally being destroyed or eaten by the mechanism.
My sony tc-we605s has the same tape mechanism - except it has two of them. Ad it's doing the same wild back and forth winding that eats the tape sometimes tangling it in the cassette shell. Now I know what to look for when I disassemble it.
Do you know if a Digital scope like the DSO138 would work for path alignment of vcr? i want just a cheap scope to adjust the path of the tape on my VCR's
looking at the usual online sellers they offer assortments of gears. I wonder how hard it would be to match up the broken one for one out of the assortment? the motors and shafts I would bet are pretty standard and probably the gears as well might be close enough maybe. the amount of parts and supplies on hand including salvage to fix stuff especially the fiddly bits is astounding. considering that most of the things made within the last 40 years were never meant to be repaired but replaced by a newer model and have just as likely have been made obsolete new technology any way
Just an off-topic curios question, Why would they mount power transformers diagonally? I've seen this on multiple devices throughout the years and I could never understand why. Even if the heat dissipation is the main reason, there is still a lot of room for the heat to escape if it was installed normally.
Power transformers emit electromagnetic radiation. Think of it like a big figure 8 with the least emitted along the axis of the core. So they rotate so the least magnetic influence is directed towards sensitive electronics like the audio preamp circuits.
Question please... i have a Pioneer CT-42 elite deck with same problem as your's ( CT-43 ) i replace with japonese Sony motor made for double deck.. i have buy some POTS (50 kohm ) with 4.7 kohm... even i see your video 6 time i don't know how to fix it....🤕
I first would treat this deck with alchool and paper. I love to have them clean as new :) I'm always amazed seeing how empty some of these decks chassis were I don''t like killing wasps especially if they are hornets. I know they are dangerous but I let them even walk on my fingers: they understand I don't want to harm them. Usually I'm able to have them get out of my window. They are really dangerous if they are close to their nest
So that's 15us which is 21 cdn then because these shippers always ship FedEx or UPS ads another 40 broker fee. Even if i could get it for 21 cdn and sell it at my cost, by the time i add 50 for service that's over what the owner was prepared to pay. They had a 50 max limit . That part would have to be 1.00 to make this a viable repair.
@@12voltvids Thanks for the video, I have a TC-WA7ES that was going crazy just like this one and now back in action thanks to you. I sourced replacement gears from aliexpress at ~$5CAD, free shipping, and arrived in 2 weeks. They sell metal ones too for about the same price so I bought 1 of each, just under $10 all in. Actually only Deck B was slipping and Deck A's motor was all gunked up by the melted belt that slipped under the gear. You're the best!
I have a Sony TC WE 825 S. That deck is a terrible deck to work on with all that plastic mechanism crap and hope it doesn't break. My Pioneer CT W 703 RS is a much better deck to work on. Far less plastic crap on the mechanism but the display will burn out over time. My displays are bright and flawless. Parts are non-existent to buy new. Ebay sellers are selling that pioneer for high prices with a burnt out display and calling it refurbished.
@@12voltvids I got a replacement gear for my panasonic F D55 boombox as its my favorite unit its my only one with cd/tape on the front and the tape has touch buttons and manual level recording. I do sometimes take it with me once in a while on longer trips. I also have a SONY TC-WR950 have you ever seen this model it was one of the last to have all metal transport and it has double side recording to.
At one point they'll be all broken and they should be ready to spend 50-100 bucks for parts and labor anyway. Vintage classics are going to go up in price, there's still over abundance in the market to give an illusion you can have one cheap, but if you don't know how to manage them you'll be quickly overrun by costs and off time.
That's not a tape eater. That's a tape devourer! 😳 I've never seen a machine do that before. What I've seen is the take-up reel stops turning or intermittently stop turning, then the tape gets wrapped around the capstan and pin roller.
Sir… sorry to get back on a different issue but seeking your support.. it is about PANASONIC RX-DT55 .. CD and Cassette won’t play only.. everything else is ok.. can you help with diagram only ?? Please
do you have a email or something i need help identifying a gear part on my vcr to order another one, just scooped a sony today slv-750hf and for the left roller mechanism its broken on the bottom, grey gear...so upon tape feeding to the head the left roller isnt rolling in sync with the right one bring the tape to the drum head since this gear is broke. I did glue it to attempt to try to fix it best I can do for now I guess.
kpcomponents.co/products/sony-3-736-147-01-gear-replacement?_pos=1&_sid=0d80e0532&_ss=r That the link to the left threading gear. The new one is blue, the original was grey or blue.
@@12voltvids yup thanks i got it all busted down to that part gonna leave it instead of trying to glue it then put it all back together, also gotta align those gears just like you did since that gear fractured and its outta sync cause of that.... just gotta order the part now, its all identical pretty much from following your video from the slvr1000
I have a Sony TC-K615S 3-head Dolby S with calibration which has the same flimsy plastic mechanism. I had it repaired by 3 different technicians. new belts don't last and it always fails. The last technician who attempted a repair told me the same as you; the plastic ages and deforms over time, cracks appear and tolerances have changed. The music search programming that systematically raises and lowers the heads several times before each transport operation adds additional wear and tear. It's been in storage for several months and unless I reproduce and replace the plastic parts with metal (3D printer) and turn off the music search, I won't try to fix this junk again. Too bad because the recordings made in Dolby S sounded very good.
Once digital recording hit, DAT, CD, MD ect, the writing was on the wall for all analog formats. The few cassette decks that remained in production all used the same crap mechanism. These were made for the cassette hold outs of the day that were not ready to commit to new tech yet. The bottom had fallen out from the cassette market. Nobody at the time expected cassette decks to be in use much in the 90s and certainly not into the 2000s. So they were built as cheap as they could and nothing is cheaper than injection moulded plastic. People whine and complain about how cheap they were made but one has to remember that they were built at a time when cassettes were quickly becoming obsolete and nobody figured that anyone would be using them for more than a few years. Now I am going to hear people comment that it wouldn't have cost much more to make out if metal. That is simply not true. Fabrication out if metal is many times more expensive. First you need the material, then the the tools and dies to make the parts. Corossion protection and lubrication needs to be applied as well. A mechanism that might cost 5.00 to make in plastic could cost 50 to make in metal. All of a sudden that 400 tape deck in 1000 but the problem is in 1995 nobody is paying 1000 for a tape deck. They want a top of the line at 399. You can't blame the manufactures. The customers dictated exactly what we ended up with because the high end stuff sat on the shelf till the manufacture decided to dump it at at a loss. How do you think i ended up with my first dtc75es and my slm1 turntable and rsm275 cassette deck. I waited for them to have several birthdays and when they were discontinued I grabbed them cheap. Rsm275 i think I paid 200 for, slm1 225 and dtc75es 300. Eventhe tdv1010 which was given to me a few years ago. It originally sold for 1400 but when JVC blew it out my friend that worked at a JVC dealer at the time picked it up on blow out price 200. Then gave it to me a few years ago where it sits in my cabinet not being used.
Great video people like myself are using cassette players everything proven people like y'all don't know there's people buying them there not hard finding it's the people who is hard finding out what is going on behind their back now days
Higher end decks still have weak plastic parts. Most do. Look at the dragon. Little white plastic gears that snap in the azimuth control. Made of unobtanium.
Don't hear you swear very often lol they are irritating baskets tho lol when we was kids me and a mate made electrics shockers out old transformers out of radios 240ac to 9v here in UK well I made one when I was about 18 and put it in a watch box as joke and got someone to open it by pressing two contacts on side I took to a friend's and gave it to his mum when she came in, she went mental and says " you know I have a Pacemaker" whoops I didn't know, another great job anyway have a great day
Not a chance in hell. I might make 500 bucks a month fixing stuff. When I did it for a living between 83 and 03 my salary was about 80000 a year. The national average over that time 30. The last year i worked there i took home 30k but by 2003 the average wage had grown to 40. The writing was on the wall.
