Hey Sweetbeats. Thanks again for the Akai mg1212s. I still have yet to finish either to a working condition, however I was able to familiarize myself with machines, and have managed to fix my mg1214 today, along with one other mg1212 and also fixed two mg14ds (rackmount version) and in doing so...

Question. What connectors does this machine use? Board to board are small JST style connectors. They are 2.54 mm pitch. I have some from various manufacturers including TE Connect, that fit as far as pins are concerned. The actual housing is what I cannot find. Slight variations in these types...

Please someone tell me what this schematic means. I understand the transistor symbol. What are all the dashed lines and 1,2,3 with circles?

I have an mg1212 that mostly works. But for some reason after recording 6 tracks.......track 7 recording erases track 1, track 8 erases track 2 and so forth.... I have 3 ripped apart but transports do work. Those are my projects. Another one which I have not messed with, but know it needs...

Is it ok to do this stuff over the phone? Typing takes sooooooo long. Is there a user policy that prohibits this?

I am an electrical novice. I know on schematics it says the 35 volt output. ......but by the transistor it is supposed to read like 39 volts. Not sure why. On one of my working machines, this voltagedrops only around a volt when play is engaged. On one of my bad power supplies, this voltage...

Yeah. I have schematics for mg1212. I am also picking up an mg1214 in the next couple months. I'm a little busy today. I have three power supplies on my bench and have just recapped one. All mg1212s. In fact, I need a little help with power supply schematics myself.

One more thing.........I finished two songs and put them on a cassette. Took them out to my wifes car, and man the bass was ALL THERE. Flipping back and forth between the radio and my tape had me convinced that these machines are indeed pretty frickin cool.

Alright. I recently got back into my machines. Heres what I know. Out of my three power supplies, only one works. One of them shows the full volts sitting on my table with a meter,, like around 38v, but when it is installed in machine and the play button is depressed, lights go dim and voltage...

I was all ready to critique your mix. Sounds good. Nothing bad jumped out at me. Good work

It physically wont turn when you try to crank shaft by hand? Its completely seized? There are plenty of places that work on motors. You could start with an electronics shop.....or even a place that repairs motors for bigger stuff could recommend some place.

I believe this thing not only requires power, also some circuitry that regulates power because motor must turn at an exact speed. A feedback that tells motor to speed up or slow down.

Yes. I just started recording on the one that partially works. I want to get 2 or 3 going so if I am in the middle of writing, I can do it non-stop. Thanks for the reminder. I love music first. The end goal, is to make a few good songs, rock/ metal. Not a crap load of filler, just some real...

Hmm. Perhaps this is the thread I was looking for. Sweetbeats and I were trying to figure out my recording issue. Turns out that I found an issue which may solve this. As you said Sweetbeats, the oscillator could be the issue. So recently, by swapping boards from different machines, I found that...

Holy Cow deslog, those pictures make me happy. So cool to see the photos. I just ordered a 14d and it is awaiting for me in Nebraska. I will be able to check it out in 2 weeks. On Eject arm, yes, I imagine re-bending would work. It is aluminum which is a real "sticky" metal. If you want to...

Hi Guys, So on a previous post I said I grinded the eject arm, which sits on left side of transport. It turns out, that is not the best idea. Apparently, because this thing is under constant tension, it gets bent. Imagine 35 years of having that tough spring pulling at you. Ever notice your...

Hey Friends, Just made my first real recording on my MG1212. MIxed results. The bad is that after recording the full 6 first tracks, I moved to track 7 and it completely erased track 1! Drums gone, total loss. Recording on track 8 erased track 2 and so forth. So essentially I have an MG6. I...
