Thanks, Jules. None of this stuff gets done by one person, of course - Dave Latchaw was the first to build one with the TSB-165A capsules that we were just then able to get via a group buy, back when

You don't need to be super picky on that or most of the other parts.? Go ahead and build your first mic before you worry too much - I'm pretty confident you'll be very happy with the

hi all -- sorry to bump a very old thread.? i am trying to do the build mentioned in the OP, but the capacitor listed is no longer manufactured.? does anyone know if any old `4.7uF 25v aluminum

Great question: One of our members, Scott Helmke, designed a simple (but excellent) version of the Schoeps circuit for use in microphones using this capsule

This is such a basic question, but please... One name that is repeatedly repeated in all mic forums is 'Alice'. What is the original source for this?

A bit of perspective on component selection: as far as audible performance goes, the only parts that matter are the capsule and op-amps. If this were food, the capsule is the cut of meat and

Indeed they are! That is a very insightful thing to say and I'm glad you're posting such high quality responses.? ;) -Scott -- ---- Scott Helmke ---- scott@... ---- (734) 604-9340

Yea, 40 years ago when I was a younger engineer, metal film resistors were an improvement over carbon composition ones of the day. Same with capacitors etc. I’m certain we will have some golden

Components not compliments wrote:

I have built quite a few of these with absolutely normal 1/4 w resistors from Amazon and they perform amazing. Compliments are really made to a high standard these days and most things will be just

Thanks for the positive feedback on my OPA mic instructable. I will look at the ".22nF" on the instructable schematic. I use metal film resistors and 1% for all of it except for the 1Gig, which is 5%

The importance of matching these resistors is quite exaggerated. For a strat, the legs going to pin 2 and pin 3 are different. One takes its source from the source of the FET, and the other from the

Hi everyone. I'm currently in the process of building an OPA Alice based microphone using a NW-700 body and TSB2555B capsule. Jules instructable is an amazing guide that makes it trivial for anyone

So yeah, I forgot to actually make my real point - what's the current flow for the DC bias? ?What's the best resistor for that Sony wireless, in other words? It might be a little while before any

There can actually be interesting coincidences in life. Ferrari are not very common. But because of the weak yen, Japan is very attractive to international tourists from all over the world since a

Heinz - great catch! And nice feel of the space. This recording is special in several ways - you managed to record not only a Ferrari but also passers by speaking in Polish. In Japan. Sure, there are

Thanks, Scott. The only reasonable images of the DPA CORE "preamp" (their word) is from a DPA promo video ( https://youtu.be/NMLvT8cYbwE?t=138 ) , where they also say each one is "tuned to match its

Scott Helmke <scott@...> added the photo album DPA 4066 capsule FET ( /g/MicBuilders/album?id=295709 ) : Closeups of the FET and other components found on a DPA 4066

As somewhat expected, the photos disappeared. The album can be found here: /g/MicBuilders/album?id=295709 -Scott

OK, so I happened to have a DPA 4066 headset capsule on my bench - I work for a company that rents out audio gear, including a lot of wireless with DPA mics. So this one showed up as unrepairable due
