I think the best thing to do is to narrow down where the potential fault is by using a pre-recorded tape (New Kids on the Block?) to check the CUE bus, STEREO bus, and AUX SEND outs.

Re: Change of internal transformer JP-8000

I know this is an old post, but would anyone have any info how this was done. I am looking to do the same for the same reason. Thank you I believe the JP8000 transformer has a few voltage markings across the top, such as 240V, 230V, 120V, 100V, and NC. Currently on your transformer, there should be...

Re: Please help Urgently! Korg M1 noise level

I also do not know if it is natural in M1 or not) but as soon as I connect it to sound card high noise appears I am going to assume the M1 and the computer/audio interface (sound card) are plugged into the same electrical circuit in your residence. There are a couple things you can try: - Power the...

Re: Alesis Micron firmware 1.1

Given the "great help" received, after having received confirmation from Alesis that the file I should have used was the one I published, but the firmware update procedure stops at 95% (now you know it). Having said that, "thank you" for not helping. Given that you have the patience and politeness ...

Re: Yamaha RX11 Repair Thread

So does anyone know what kind of transformer is needed, should I try and fix it? ;) I am usually the first to advocate for repairing things (sometimes irrationally), but I would consider just parting it out. I'm a fan of Espen Kraft and all, but his claim that it is "one of the best drum machines e...

Re: Gotek and FlashFloppy E34 error

So I put the FF.CFG for the EPS16+ and the img (800k) for the OS1.3, and... still get the E34 message. I try a different USB stick, same E34. I had tried the hfe (1961k) versions, still the E34 message. If you have the normal 3-digit number display on the Gotek rather than the OLED upgrade then the...

Re: Ensoniq SQ-80 Front Panel Button Problems - Please Help

Maybe I am totally misunderstanding something? Probably not. All I've had to go by is schematics, and those schematics aren't even 100% for your board revision :D It's entirely possible that almost all of the little caps are decoupling caps for the ICs. And the cap which has one leg not connected t...

Re: Ensoniq SQ-80 Front Panel Button Problems - Please Help

I cannot find C23. The schematics are a red-herring of sorts because your revision of the display board doesn't match. The components will be numbered differently, although the concept is still the same. GENERAL TROUBLESHOOTING CONCEPTS FOR ENSONIQ SQ80 KEYPAD FAULTS Ensoniq SQ80 Key Matrix (7x8 al...

Re: Ensoniq SQ-80 Front Panel Button Problems - Please Help

Well unfortunately, it does look like the Rockwell 6500 is at fault. The whole length of trace and all of the switches pass the continuity test. It wouldn't be the first time, but double-check that there isn't a bad solder joint on the 6500 or something shorting that pin, etc. I would check that th...

Re: Ensoniq SQ-80 Front Panel Button Problems - Please Help

Also, my board is a revision A board, while these schematics are for revision C. The schematics are good for the purposes of illustration, but you don't even need them to test this issue. All you need is the general concept of how the problematic buttons are tied together. Since we know all the non...

Re: Ensoniq SQ-80 Front Panel Button Problems - Please Help

Also, I can now confirm that the buttons in question do not work while in test mode. I believe this eliminates a software issue as the potential cause.
