Authentication popup?

Anyone else getting two autnentication boxes popping up for every page they load?
A username and password are being requested by http://openx.tapeop.com. The site says: "Please Login"
I'm getting it on both Firefox and Safari.

Is this legit?

Did it just steal my TOMB password?

Having seen & participated a couple of comparisons of Auratones (such as the one in the latest print-copy Tape Op), it appears that there's no single canonical driver. I'm guessing that they got whatever full-range driver could handle the power, and put it in a little sealed box. Having recently red...

As Drone says, IR LEDs are pretty common, but they're mainly used for stuff like TV remotes and motion detectors, where they produce beam that's invisible to the eye. They aren't a good means of heat transference. The couple of parts I just checked in datasheets are rated to less than 0.1 watt max d...

My experience with the KSM mics is that they're remarkably good...including the KSM27, also. They're not emulating anything, they're just very usable. Coming from a company we usually regard as making tough dynamic mics for live sound applications, they're even a little surprising. The mid-line Audi...

The official datasheet has one more word on it: http://www.analog.com/media/en/technical-documentation/obsolete-data-sheets/139484016SSM2017.pdf The huge "obsolote" stamped across every page. They've been superseded by the SSM2019, which is available, and priced like the THAT parts. ICs from China a...

I've got a couple of condensor mics that would work with a pad that can supply phantom power, nothing more.

Of course, I'm a rock drummer, so I don't usually tax the noise floor of my gear.

In general, direct outs are post fader.

Looking at the GL2 docs online, it looks like there come cuts & jumps to configure where the direct out is in relation to the fader.

Thanks for the schem!

Are J111's still obtainable?

Last time I met with a Fairchild rep, they were telling me that all through hole parts were going to be EOL very shortly.

Mackies tend to run warm. I've got an original 1202 that gets significantly warm near the power switch. Warm is OK. Hot is not. If you can't hold your finger on it indefinitely, a> something is wrong, and b> it's a fire hazard. The 1604 VLZ may stem from the counterfeit electrolytic capacitor days: ...

Fulltone has been making both tube and solid state Echoplex clones for about a decade.

Their pricing makes the TRex look like a bargain.

If cost is a concern, opamps (or the THAT chip pres) are probably the best bang for the buck. Unless you've got parts to scavenge, a modest HV power supply probably runs $50 in parts...$35 transformer, a couple of $5 400V caps, etc. Most tube mic pres need input transformers, and you'll probably wan...

Also, what's the source of the schematic?

I'm kinda curious about what they say about the "see text" resistors.

Careful with your parts numbers here: it's 5534, not 5334. You'll have trouble sourcing 5334's.

But yes, a `2 is a twin `4.

And those circuits are basically the "diff amp" configuration I mentioned.

The THAT 1510/1512 are probably the best bang for the buck, low parts count preamp chips around. Add a 1646 if you need a balanced output. You could always wire a 5534 as a diff amp with gain...or build out the front end with more opamps (instrumentation amp config) or transistors (which is very clo...

Before anyone gets too excited: those are Centronics, not Tuchel connectors.

Tuchel's look like this:

Not a bad deal on a TT bay that large, though.
