Input transformers have arrived. If you would like yours *before* the semiconductor kit, please let me know. You'll have to pay shipping and packaging twice, but it won't be more than a few dollars more probably. Just let me know.

dude, there is a board game version of that now, check Target, etc.

If anyone is still interested in these, Chris is doing another GB IIRC.

uh huh. nods. yes. right-o.

can you get some?

obviously

interesting idea. Seems that you'd be running the opamp very close to its limit. Here's another interesting one: http://www.mskennedy.com/client_images/catalog19680/pages/files/131r-.pdf Even lists electrostatic transducers as a typical application. Datasheet is prelim though, but at least it's a new production device. Wonder if I can get "samples". Looks to be a pretty impressive little device.

hm, I always assumed they were of Russian design, as I see a lot of people there working them on the metro and what not.

sounds like a feature to me!

thanks guys, I'm talking to a US distributor and trying to pretend to be a company Also, looks like PcX sale that includes 20% off resistors is coming at a perfect time for us!

Have you tried adding moar piezos to the PSU?

Ponzi scheme?

Buy a Singlepower, wait until it burns your house down, collect insurance money, then buy both.

Why use the 6CA7 again? I don't follow. not the PA42, but stumbled upon plenty of these for beans: http://focus.ti.com/lit/ds/symlink/3583.pdf I was more curious on how it compares to the AC coupled amplifier.

might be worth it for you to hold one of those cool wires to your right temple and one to your left temple for a few seconds.

what about this one:

I've charged mine a couple times already. Works great for me, just need to raz them about the wierd-ass power connector on my Chinese DAP and see if they'll make good on providing "any" connector ")

I really love the upper register, so I wouldn't add a supertweeter. They are too hard to integrate well and I don't like the phasing complications they introduce. Most designs are pretty much flat to 20kHz and go around to 45Hz all at +-5dB or so. Case in point, the Alerions. Good enough for me.

here's the original I'd love to try a Lowter driver at some point, but they're amazingly expensive.

Is the GES the AC coupled version, or the DC coupled version? Also, how does the AC coupled circuit compare to the DC coupled circuit soundwise?

not even the TP-1?

what, does it have some sort of solder prevention circuit installed?

try adding a parallel resistor from the wiper (i.e. output of the pot) to ground see if that fixes the problem.
