Parts list for a nice looking U87-ish DIY mic

Ok, let’s face it… a DIY mic built with a BM-700/800 mic body is fine if you want to record on your home or you podcasts. But if you have a recording studio and your clients will be visiting you; having a mic built on a cheap BM-700/800 mic body may spark some concerns on

Quick info about new Mouser BOM for PA DC V.56

Some quick information regarding new Mouser BOM for HL Pimped Alice DC V.56 PCB: 47R5, 2k2, 82k5 and 100k resistors have been selected to be 0.1% tolerance. No need to pair mach anymore. All ceramic capacitors with the exception of 1uf (C21) are C0G. I will change this for a film, but space is limited.

New PCBs with DC converter are ready!

Hi All! The new HL Pimped Alice DC-DC PCBs, with included DC converter and ready to ship! HL PA DC V.56 EBay Link can be found here: HL Pimped Alice DC V.56 Ebay Page Link Premium Mouser BOM is available here: Premium Mouser PA DC V.56 BOM Link This is the schematic for HL Pimped

New Pimped Alice with DC-DC Converter Coming Soon!

Hi ! This will be the new PCB to be released pretty soon. It’s a single board PCB with Alice circuit plus a DC-DC converter, to provide 55-65V for LDC capsule polarization. It’s partially based on Herry Spragens design, published on his Audioimprov.com site. More info on the next few days! Regards!

Alternative Minimal BOM from Mouser

As noted by some of you, PF5102 JFET has reached EOL and is no longer available from Digikey. As Mouser still have J305s from InterFET available, I have created an alternative regular (non-premium) minimal BOM from Mouser.  Here is the link to the Mouser Minimal BOM: https://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=1ad69b8213 Enjoy!

Vertical Capsule Base for JLI TSB2555B capsule and BM800 style mics.

Hi! This capsule base is for use with the TSB-2555B capsules from JLI and BM-800 (cilynder) style mics. Instead of picking sound from side, it could be used to pick sound from top or front of the mic. Useful if you need  the mic directly pointing to a sound source. Used successfully on this mic:

Digikey BOM for a minimal Alice Mic Build

On this link you will find the DigiKey BOM with the components required to build the minimal Alice Mic, as shown on post FAQ (5). http://www.digikey.com/short/jbp11q It’s 4.70 USD total. Standard quality parts (no fancy resistors or capacitors) with no spares. Just the exact number of parts requied to build one mic with this config. At

Frequently asked questions on Pimped Alice V.40 PCB (5)

What components are recommended to be pair-matched, to optimize my PA V.40 based mic? Honestly, I have built Alice based mics that sound really great with no pair matching at all. But, as some of us are a little bit perfectionists and don’t want to leave anything to chance, here is the list of components that

Frequently asked questions on Pimped Alice V.40 PCB (4)

What’s the minimal configuration of components I could use to build a working mic with the PA V.40 board? Minimal configuration of components for building a working mic, will be the equivalent to Scott Helmke’s parts list for the original Alice using an electret capsule like TSB2555B or TSB165A, as described on his webpage: http://scotthelmke.com/alice-mic.html

Frequently asked questions on Pimped Alice V.40 PCB (3)

How do I bias the JFET of my Pimped Alice V.40? JFET may be biased with two purposes, first is to maximize headroom, and second to minimize 2nd harmonic distortion. Second option won’t be described here, as it requires specialized equipment and/or conditions, sorry for that. This method assumes your PCB has been populated, placed
