Doepfer

check the fuse and the transformer (output).

Hello!

It looks like I've gone and fried my G6. Today I installed some new modules and a 5V adapter (yay!) and suddenly the G6 just didn't light up anymore. I couldn't find any fault in my cabling, but the fact is that the G6 is dead. No leds light up. I have a G3 as well, and I tested each module that was in the G6, and they aparently survived whatever happened. Happy happy (I was really cold sweating there for a while). Except for one module, maybe. When I installed it in the G3, the same thing happened, and now I'm a bit short on power on the Eurorack side of things :-/

So: where to start? I don't see anything that has obviously burned, and there were no visible "hints" when it happened. I'm not the one to go probing into anything with current. If the G6 and G3 are easily fixed, I would like to know it. Also, I'd like to somehow test the module that appears to have caused this, if it actually is faulty somehow, or if I just screwed up.

Could this be a case of ribbon-off-by-one?

Any hints appreciated,

Kim

If a ribbon was "off by one", -12V would short to ground.  That would certainly be a problem.  But it seems like if it happened in two rack cases, the problem is at the module end of the ribbon.  Check that right away to rule it out. 

What module is it?  Is it new?  Have you used it before?

Nick

Hi guys!

Yeah, I thought it sounded like a fuse problem, but I couldn't find it
yesterday when I was panicking. But just now when I checked, the fuse of
the G6 is blown. Have to leave for work now, but I trust the G3 problem is
the same. That would sure be a relief.

Stocking up on fuses today, then...

Still, I really wouldn't know how to check the potentially faulty module
without plugging it in. It's the trigger delay module, and it has worked
for me before.

Cheers,

Kim

Had this same problem.
Added some new-to-me used modules of dubious quality and zap, down goes the
rig.
T'was the fuses, replaced both and added another PSU (tiptop uZeus with a
beefy 6a regulated PSU)  and now everything's happy.

Hi!

Got some spare fuses now, and I'm set for the next adventure, but I have
another question: in my G6, there is no cable going to the +5V connector in
the middle of the bus board. Does that mean that the 5V adapter doesn't
have a source for its 5 volts, or is it supposed to be that way? Didn't
check the G3 yet.

I have an "old" G6, which apparently delivers 650 mA's, so I may need to
get the calculator and module documentation. But it is nowhere near full,
so I hope that was not the problem. Still, would it fry if the modules draw
more than it can deliver?

Cheers,

Kim

The doepfer 5v adapter draws from the 12v rail so no cable. You may need to add a cable between bus boards if you want 5v to be on all bus boards. Personally I don't, I just have the few modules I own that require 5v running from the same bus board.

Before installing the fuse, did you get slow blow fuses? If not then they won't last long at all, in fact will probably blow as soon as you provide power. The current draw is important, but it shouldn't fry if you overload it-that's one of the things the fuse is for. Also consider the current draw values to be an approximation, not absolute. If your total using is above about 580 I would assume you are

Oops finger slipped.

I was about to say I would assume you are running at full capacity. That means you need a psu with a higher current output.

OK. So the adapter is needed precisely because the 5V is "empty".

Yep.

I'll check where I'm at currently (pun!). Leaving for home now, with my bag
of fuses...

Sorry I seem to be having some email problem today, with it deciding to send when I am halfway through typing. The 5v low cost adapter is designed to provide up to 100ma but it takes that from the +12v rail. So straight away you've lost some of your 650ma to generating that 5v. I'd still expect the g3 is probably getting enough juice but the g6 may be getting close to its limits if its the older psu version.

What I was trying to say at the end of my last message is if you're getting close to the current limit you should consider it urgent to upgrade your psu ASAP. It's not good for the life of your equipment to constantly push it to its limit and it may exhibit strange behaviour. My own experience lead me to believe my brand new (at the time) e340 cloud generator was faulty. I was using 1100 of my 1200ma according to my calculations. Installing a 2nd psu fixed the issue immediately.

Hi!

I put in new fuses and re-arranged the modules, and everything now works. Kind of. I put the 5V adapter and the "new" modules in the G3. The "new" modules I have are some AS drum modules and an MFB drum sequencer. Problem: The MFB triggers the drums, but only the trig led lights up and there's no sound. The MFB does successfully trigger my dotcom envelopes, and the Oberkorn triggers the drum modules with sound, so apparently the MFB and the AS modules just don't work together, which is kinda surprising.

But this is probably the wrong forum for this problem

Thanks for the help, guys!

Cheers,

Kim

More than likely, this isn't a problem with the back of the modules, but the front.  To properly, audibly trigger the Analogue Solutions Concussor modules, you need to give them more than +5V as a trigger input.  I'm not familiar with the MFB drum sequencer.  If it has the ability to output a higher voltage, say +10V, that should do it.  Is there a jumper for that?  If not, you may need to buy a few A-183-3 modules.

This advice is given without warranty, but is based on my experience with the BD-88 and SD-88 Analogue Solutions modules.  I believe they're heavily based on the TR-808, which wasn't using TTL standard voltages.

Hope that helps,
Zoë.

Mfb seq-01? Read the manual. Trigger voltage level can be changed, it's probably the voltage level is too low to trigger the as drum modules but high enough for the dotcoms

Hi!

No jumper :-(

If I route the trigger through my trigger delay module I get audio from the AS drums. So this can definitely be fixed with more modules :-)

Cheers,

Kim

If you're using an MFB SEQ-01, then read the Triggerspannung section of the manual over at http://www.mfberlin.de/Manual/SEQ-01_b.pdf (translating online if need be).

Hope that helps,
Zoë.

Heh, I probably should :-)

Ha! No jumper, but the voltage can actually be changed from the front panel directly. Nifty. Maybe I really should read manuals more often :-)

That made my day, thanks :-)

Cheers,

Kim
