Plase find attached the schematic of my MicBooster. It's not the most perfect in the world, it can always be improved, but it's used by hundreds of discerning users around the world. I had one of

I'm quite the opposite... I managed to squeeze 14 bipolar transistors (packaged in matched pairs), 21 resistors and 5 capacitors into a FetHead-style body. It's a true fully differential amplifier

Remember one thing: the smaller it is, the easier it is to be stolen.

They also have "barrel"

I bought a few samples. There is not much space for the PCB. I don't want to go SMD so I had to give up. The price is quite attractive compared to the Neutrik solution.

That's what I used for my MicBooster. The space is good for conventional through-hole PCB.

Thanks for the suggestions, this gave me the idea to look for other clones, and I found this: GAZ-MA1 MINI Dynamic Microphone Preamp ( https://www.aliexpress.com/item/1005006372538382.html ). It's not

Yuo might even consider using the enclosure of one of these: https://www.aliexpress.com/item/1005006647753658.html It's a sort of Cloudlifter 'clone', and is a robust enclosure - complete with XLRs

Jan, what is da KF parameter?

There are also these enclosures on Ali: https://pl.aliexpress.com/item/32961610296.html?spm=a2g0n.order_detail.order_detail_item.3.577743cexag7lb&gatewayAdapt=glo2pol Cheap and sturdy. Note, there

What about something like the Neutrik NA-Housing? https://www.neutrik.com/en/product/na-housing You can match it with their D-shape modules, like the NM3MD-B and NM3FD-B XLR connectors, to make a

You might be able to find “mini” sized guitar pedal enclosures more easily than cylinders or tubes. See attached photo. — matt.

I am designing a "mic activator" with some design goals that are not satisfied by the simpler ones (e.g. FetHead, CloudLifter), but are possibly already done by the more complex ones like SE

When doing noise simulations on JFET circuits, check out the KF paramater of your JFET model. If it is not present in the parameters list or has the default value of 1E-18, then the JFET model cannot

This is a complex issue ... actually 2 issues as Henry points out.? I pontificate at length on this in LNprimer.pdf in my Files directory which also has loadsa important references. Here are some of

Gotham’s assembly instructions for GAC3** recommend tying shields to pin 1 at both ends, and leaving the ground lug of the connectors

That's what this thread is for. If you see a good deal on a mic body, let the group know. If you buy one, tell us about it, since a lot of the cheap mics are junk inside, but some can be improved.

I have always found LTspice noise simulations to be quite accurate, as long as the models are correct, which is not always the case.

Not trying to hijack the thread but the title somehow fits and creating a new thread just adds to the chaos ? Anyway, I've foumd this on Ali, might be interesting, the price is OK I
