... I'm just wondering if Brass will solder with normal electronic ... Funny you ask about this now. This weekend I soldered some brass tubing to make an ORTF...
Wow - that's a beautiful mic! In regard to the original question about brass mesh and solder - yes. I use regular Kester "44" solder on brass (and sometimes...
... Sony? I'm assuming Panasonic. The question that I have is How in the heck did you get the microphone elements to fit in the end of the brass tube? I've...
... D'oh! You're right, it is Panasonic. (Now I gotta fix the picture titles!) ... I made a shim of the thinnest brass sheeting I could find at the hardware...

hello, I'm taking a look at the linkwitz mod for the wm-61a (well it's actually for the wm-60ay, but, cross-referencing things he says on his site makes me ...

Hi Pietro, Cannot see the schematic. Must be this one: www.linkwitzlab.com/images/graphics/microph1.gif . Are you refering to the 2c drawing? Everything on the...
I'm assembling the Alice mic and I noticed after ordering my parts that the parts list left off a 2N4416 something-or-other shown on the schematic. Yes, I'm...
... Oops! Guess I need to fix the parts list. The 2N4416A from Mouser is what I use, too. ... Or just get close, like 310 or 350. Two in series would be...
Hello Bertho, ... dial-up phone ... OK, didn't know that. I hope all will be OK after the hurricanes are over. ... Basically I just want to understand the...
Hi, Do you really use the Panasonic WM-55 capsules "as they come" for recording? The data shows a dramatic roll of at lower frequencies. Seems to be optimised...
... It's more to do with personal choice. Most of my recording is of piano, horn, or church music where that particular rolloff is not as much of an issue. ...
... I found that while there is a low-end rolloff, it's pretty easy to correct with a bit of EQ. The information is still there, so a little bump on the ...
... correct ... on the ... Exactly. This reminds me, my Sony minidisc MZ-N707 has +1 (SOUND 1) and +3 (SOUND 2) bass enhancement settings. The documentation...
My way is to fixture the parts and apply solder paste, which is available in small syringes. Then I put the area I applied the paste to, between the tips of a...
... The TS capsules that are similar to the Panasonic series are basically about as noisy. If you go with the ones that require an external FET and 1Gohm...

Hi Scott, I agree with you, but in some situations you cannot clean overall resistor body surface with cotton swab if it soldered to PCB. In this case try to...
I'm trying to come up with a stealth recording solution using the Alice circuitry. So far, my projects have had the electronics start within an inch of the...
... Well, if you're on a circuit board you'll have bigger leakage problems than skin oil - teflon standoffs or point-to-point wiring is recommended for 1Gohm...
... I've found that putting the 1Gohm resistor and fet on the back of the capsule is best - you don't want a long wire at those impedances! But it's no...
Yes, I agree, and if you cannot use teflon, use some good coating lacquer for cleaned FR4 PCB. Similar process is used for coating transformers... using...
