Hi, a guy sent me a Yamaha K that needs to be fixed. I think this deck was brought to a shop before I receive it and they was not able to fix it because they replaced the reel motor by a I think this “mod” has burnt something in the power supply because the logic control and the tape counter doesn’t work.

Also noticed that the reel motor driver is hot even without a reel motor connected on it. Does anybody has good quality schematics of that deck? There is the sm on Electrotanya but the schematics are unreadable and some pages are missing. Last edited by 20tajk7; at Find all posts by 20tajk7.

The EG motor is not the bad choice as these motors are the only stock solutions to the motors that are burned up or worn out.

I have used EGD-2B capstan motors and they can do the job. The reel motor is not that hard to sub either and it is just a matter of screw hole positions, thread type, shaft diameter and length. The biggest problem with Yamaha deck is that you can get any parts for them and Yamaha like Sony does not care to even deal with it- they want to sell you a new item.

To me that means go buy another brand. Firs order of business is get voltages back to where they need to be, then ha6109 looking for the parts to get the deck working again. It is possible that the reel motor driver is like another BA IC or one of those.

You can also search datahseet recovered parts from other decks that were good and then there is the Chinese market. So far my experience with a company Hexunda was very bad but not all companies over there are up to no good. This is one of the first things the blows out when people use the wrong power supplies.

This is also the 3 V speaker amp source as well. Very special and not made in any other IC that I know of.

Of course your direction forward all depends on the head condition. IF it is worn out then your deck for whatever is left might be a donor deck for parts. Oh, I forgot to mention- now you see why I dataasheet paper manuals- go to stereomanuals.

Same thing happened to me with RT PDF no fix, paper manual fixed. Find all posts by Skywavebe. Your photo is not showing up in the thread. The reel motor is driven by a BA, a not-very rare part. You should be able to find one without too much trouble. But you dahasheet need to see why the supply voltages are out of whack. What would be very difficult to deal with is if the capstan motor drive IC is bad.

The DD motor va6109 fine, the problem is on the reel motor and his driver circuit. Here is the pics of the motor: I’ll try Stereomanuals, I hope shipping to France will be not too expensive. I’ve tested the BA, it heats, consumes mA and doesn’t make running the motor even with the good binary code on the input pins. Well, I can understand that, because that capstan motor has its own set of drive electronics inside and definitely does not want to see reverse polarity, which is what that BA will deliver in rewind and slack-removal modes.

God only knows what’s happened to the driver in that situation. You need to put a correct reel motor where it belongs and probably replace that BA If it works with the Sanyo motor, then it’s fine. If it does not, it’s probably not fine. Hi, just received and replaced the BA, it works fine, now I need to put a new reel motor and make some adjustments of the recording circuitry left channel 1dB off.

Where to buy a good equivalent of the BFS-7B? Hi, I received a new Mabuchi RFTB motor ordered in England, when replacing the reel motor I took the opportunity to clean the idler tire but it has also been modified -First as you can see the “Jesus” clip was lost and replaced by a piece of plastic. I promised to the owner to fix the deck so now I cannot give up.

The deck was obvious worked on by butchers. I kind datashfet wondered why a Capstan motor was used where a reel mote was required. The there is the glue situation. Well you know you have been working with genius when they blow out regulators. The Idler they put in was for a play idler of a different model.

This one can be used in the Teac A You might want to go through other parts decks to see if you can get the right assembly to work in that deck. Being here can help due to the large amount of decks that are possible to access. I have a lot of Teac Idlers here but not sure how they might fit on a Yamaha deck. I also have a good assortment of E retaining rings if you want to go back to that. I have collected them off of all kind of assemblies that otherwise would have been thrown away.

I bx6109 if someone could provide a picture of a correct Idler for that datxsheet we dagasheet get more in the way of donations.
