Thank you Germar! The final version of the PCB will be available as a PCBWay Shared Project. Just would like to have any feedback from the group before it goes

FWIW: I still use that technique to protect tweeters in DJ speakers... Op wo 13 apr. 2022 om 11:34 schreef Arjay 1949 <info@...>:

This technique reminded me of the same thing that was employed in Hammond organs, back in the day (1960s/70s). They used light bulbs to 'limit' the drive to the inductive drivers on the spring reverb

Hey Homero, what a lovely way to remember P@T and a great idea too. I have only ever used the fetzervalve (FETs or Valve) as a guitar pedal and never would have dreamed of using it in a mic! Any

No. They use small incandescent light bulbs. This type of passive limiter requires substantial level to operate. The signal from a microphone is too weak, so it must be amplified. That means there

HI folks! As some of you may know, one of the dreams of our friend Patrick Davis (aka. P@T, Enjoybiking) was the idea of designing a mic that could have the "tube" sound, but that could also be very

... Said bulb, as it starts to glow, becomes higher resistance to signal, functioning as a form of audio compression... Probably a Vactrol optically-controlled variable resistance.? Like: vactrol:

Though not Mylar (and not as tough), you maybe could try ultra thin aluminum like the ribbon mic folk use: https://lebowcompany.com/pricing ( https://lebowcompany.com/pricing ) could spray coat one

Was looking around at passive limiters and such, and came across an interesting implementation in “Lamplifier Microphones”. ?From what I can gather, the microphone has an internal preamp that

I have reskinned damaged capsules with aluminized mylar unrolled from film capacitors. The lower the voltage rating, the thinner the film is.?The capsules have sounded fine, though likely not good as

Well that's precisely what bothers me: there seems to be no options... I'm not a big fan of the 58 sound, and would like to get something less hyped, more extended...

I've tried different Chinese companies?for 57 and 58 diaphragms advertised on EBay. At about ?4 to ?5 delivered I'm in the UK and cant tell the difference live on P.A? (I HAVE OTHER GENUINE SM57

I went to AliExpress to see: there is a great many choice of capsules, unfortunately with about no information at all. Nosem and Takstar brands seem to be the most widespread. It's like shooting in

Hallo, sorry for my mistake. But, please let me say something to your comment. Just to clarify, you‘re saying that Most backplates are made out of solid brass. You are completly right and this was

Hi Ralf, It's not me that's building a capsule, it's michaeljtbrooks. However, I can make some comments: "2- /the backplate cannot be stiff enough. That is one reason for partial cancelation of

Hey, Jerry Lee, my namens Ralf and this is the first reply in this forum. I‘ m writing from Germany so please excuse my bad language. About 10 years ago I made a very similar experiment wich I

Whatever few ohms there don't matter compared to the Gigaohm input resistance of the Alice circuit. Look elsewhere. Surely 20 micron thickness does not help with sensitivity, but all the parasitic

It is more of a relative observation. A Chinese K87-style capsule with exactly the same circuit gives a hotter output, requiring 11 o-clock on the gain. Headphone amplifier: Behringer DX2000

Interesting project. I made a basic omni circular capsule many years ago (I had access to a friends lathe and pretty well equipped workshop at the time).? Diaphragm material was an issue (especially

What impedance converter (head amp) are you using? What polarization voltage (bias) are you using? What preamp?
