Re: 4U / LW format questions (possible new modules)

The schematic is a visual tool aimed at understanding the circuit easily and quickly. It is a representation of the circuit which has...

Re: [AVAILABLE] TTSH V4 Build Thread

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.

Re: Behringer ARP 2500 modules

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...

Re: [AVAILABLE] TTSH V4 Build Thread

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...

Re: Readymade solutions for mounting a prefab PCB perpendicular w/ a panel?

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!

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?

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.

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...

Re: Arp 1601 Sequencer clone

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 ...
