schematics circuit One could indeed have read circuit instead of schematic there, and I feel both could be valid The circuit is the components and their connections. The schematic is a visual tool aimed at understanding the circuit easily and quickly. It is a representation of the circuit which has...

Did you scope the emitter to see what's there?
Might want to try *any* other Op Amp too. Doesn't need to be 301.

KSS

Not only cutting out, doesn't sound pink either. Z2 in the original schematic is the pink noise element. If its compensation is off it could be the problem. Behringer might be using a dual -or quad- OPA, and may not even be using 301s. Can you share a PCB photo? Have also wanted to ask for a photo o...

Flounderguts nailed it.

Hope this won't be taken the wrong way. Am not a supersynthesis shill! Happened on their site recently and saw the similarly priced :75: PHRSR module. I don't have one and only read the blurb at the site but I can imagine it would be an EXCELLENT cohort for this 2OPFM module. So if you're already th...

What are you using for the noise source? Transistor or diode? Which P/N? EDIT: try another noise tranny or diode instead of the one you're using now. <--Realized this was going to be next advice anyways -depending on your reply to the P/N question above, so may save time to say it now. Edit2: And ch...

Or just use any other garden variety opa. There's no magic in the 301 type at this position. Even a 741 will likely be ok. A newer fet input type might need some compensation due to its much higher slew rate. If you've got a TL071, give it a try. Probably will have high freq issues. But will be furt...

Glad to see someone making the distinction -again- between sound and behaviour! Too often the focus is only on the former while the latter has a HUGE impact on everything.

KSS

You're probably also going to need to take into account some RF-EMI solutions. The interior of a modern synth and an old AM/FM radio are not going to be the best bedfellows! I'd put this at the top of your list.--> Check that the radio is going to work at all installed in your case. From a reception...

KSS

Components should be placed as close as possible to where they're needed according to the schematics circuit, and one should be able to find back the schematics structure when looking at the floorplan , I may be mistaking your meaning here, and if so, my apologies. The idea that a schematic bears d...

They probably get an audio upgrade at best. AKA different -faster slew- op amps.
But if the Blue and Gray sound better than the B2600, there has to be a reason, right? So how are they different circuit or parts -wise?

KSS

As i said, I was waiting for papz answer. And it didn't disappoint.

Why not simply ask your friend what he<--your friend- thinks is a fair price?

and shrunk to fit the small small desks in small rooms of people with small budgets.

It's shrunk to save cost. That it then fits better with what many potential customers is a side benefit. But surely not the driving force behind the shrinkage.

Liked your ST replicator thought too! So true!

KSS

I think getting the feel into the right ballpark is probably good enough. Yes. I agree. But that's why the pin length is the one -non B biz related- thing that would keep me out of this one. As a DIY person, I've looked at how B has made their matrix and I think one could add a middle 3DP part and ...

Mixer, slew, comparator. Repeat until space is used up. I don’t get it. None of these are sound sources (unless you feedback the mixer I suppose) or even create voltage on their own. What am I missing here? Yes, it requires you think in atomic terms. AKA weirdly. ;) But is FAR more powerful than yo...

@OP
Get in the habit of discerning and distinguishing 0V from GND. And also signal GND from Frame GND, or TE aka Technical Earth.

It will pay off dividends the rest of your time in electronics

I have found some dual concentric pots but they are horizontal and I would not be able to place them on a pcb with the jacks , parallel to the faceplate. Even if-when you do find them it's *highly* unlikely they'll work with the jacks you use that fit typical 9mm single vertical pots. The DC's will...

I'm with guest on this one. 100% Notice Neil doesn't respond to his statement, but makes a shift-key ad hominem attack instead. I was 100% with guest before that, but it's something seen often when Neil posts in threads. For what it's worth, David Dixon aka Dr Sketch and Etch is also in favor of usi...

The Ghilmetti alternative widely used todaysalso are thicker. But preserve the length. The Ghilmetti interior contact arrangment is what B cloned as well. Since both this and a longer B version would still be physically stronger than the easily broken Sealectro's, I'd want them longer. Patching thes...

Trade the diode for a second resistor. The 14V is constant, so there's no need for 'limiting'. Only scaling is needed and two resistors handle that fine. To define which way round is correct: Use a standard patchcord of the type you usually use and cut off one end. The odd new endshell you add will ...

KSS

How many angels.. But still no one's commenting on the very real difference in use between the matrix with long pins as originally designed, and the too-short version Behringer went with. Edit: Those types of things will actually affect how you *actually* use it. Compared to the originals. Regardles...

KSS

there was a post on GS, where someone received a response from B that the quote in the video about upgraded components in the blue/grey model referred to comparing it to the original, not compared to the standard B2600. https://www.gearslutz.com/board/showpost.php?p=15247763&postcount=125 I'd be su...

I look forward to papz reply. In my mind, the fair price for a 10 year old Cornwall would be whatever a new identically outfitted Cornwall is selling for today. I'm sure any offered at that price would be scooped up immediately. That's *not* to say this is its current 'value'. Or that the vintage on...
