nice! With your loop, won't you have the input RC filter from the amp transferred to the other input? I would think this would have some unintended consequences... I think it's worthwhile to move the feedback resistor like Craig did. I noticed Kevin did this in the second board revision, so I'd assume that he would agree. If you don't have a scope, I'd also add the additional 5pF/1kV caps across the 100K resistors as well (IIRC, Craig ended up omitting these caps and the 2.2pF caps, but I wouldn't do this unless you can verify the results, including transient response). I'm not sure if Craig ever posted picture of the modification, but it's not too hard to imagine what he did. Also, has anyone else done the mod outlined below? If so, I'd be curious to see what your thoughts are. https://picasaweb.google.com/inuponken/T2#5566996623938911634

I really enjoy Plymouth, and a Plymouth G&T

Kerry, just noticed this question. I used Mouser 534-11012-R (and presumably 534-11012-. I like them, my only complaint is that they are hard to get exactly centered with respect to each other, as the hole in the PCB is rather large and they sorta float around in the hole... but, that's a minor complaint.

aaaahh.. thanks! I like the idea of not having to use a drill press though, so we'll see if I have steady enough hands. Thanks guys!

ah. Thanks! I think I'll try out this one: http://cgi.ebay.com/Double-End-Pin-Vise-Hand-Drill-w-20pc-Twist-Drill-Set-/180674981496?pt=LH_DefaultDomain_0&hash=item2a11116e78#ht_2458wt_907

Thanks Kevin, I was actually looking for the tool for another use. I didn't realize a drill bit would accomplish the same thing, until I thought more about it... I just had the word "reamer" stuck in my head I guess. Did you stick the bit in some sort of hand tool then? I figured many chucks wouldn't down go down that low..

Kevin, What size reamer did you use to enlarge the C3381 holes? Looking at MSC, I'm seeing the smallest as 7/0 which is 0.0497" to 0.0666". I'd like to pick up a similar tool and am having problems finding something.

I think the Red Vodka Mind Eraser was extra effective on Al. You really don't remember?!

Cool! I definitely enjoyed listening to Al's DannyB 300B amp. I'm not sure if he is watching, but man I'd really like to own that amp one day... but the force is strong in the Voltron black hole of audio gear. well, shit, the power of marketing is great, huh? I agree. I'd say other than the 100% DIY options (meaning, it's possible to buy a 100% assembled Paramount) I"d perhaps consider the Assemblage 300B as well: http://www.audioxpress.com/reviews/media/GA400HA1.pdf Any details on this setup that AKG used?

I'm totally pissed, as I finally found another site a few weeks ago that would ship a few bottles to me and finally got around to placing the order today. At the end of the checkout, they say that they cannot ship to a list of states, and then at the end they say "AS OF MAY 23rd, 2011 THIS INCLUDES TEXAS". Argh!

Right, an insurmountable challenge to overcome, my bad.

What's interesting about the Cary? What about the Bottlehead Paramount 300B in comparison?

Good move. You would have found that it's not really possible. Amplifiers are designed with very specific target parameters. This is especially true of vintage equipment and specialty equipment. Strapping something on with a vastly different impedance plot, and thereby vastly different TS parameters is asking these amplifiers to do something they aren't designed to do. In many if not all cases you end up with a distortion FFT that looks like a RSA amplifier and discriminates against no distortion order. I think the K1000 seem to favor a small, class A solid state amplifier. I'm not sure how these high impedance cans can really be "current hungry" or need insane wattage....those are just myths that are perpetuated without any basis. Many headphone amps run out of voltage swing with the AKG, for example amps made for lower impedance loads... I think people get this backwards and reuse the mythical "current hungry" phrase that seems to describe the inexplicable need for a bigger amp. Regardless, they are unique and fun headphones. Enjoy!

Wouldn't that imply that the K1000 is a poor choice, given the notch filter that they employ?

I think it's rather interesting to note who hasn't posted in this thread...

Vitamin Water and Z-Pak.

Shelly, Creme de menthe is on my list. Is the light or dark version more versatile for cocktails? I notice that Marie Brizard has both... Not that I can get it here anyways...

Jim, what other books do you have, and how would you rate the various books?

Leave now. Who cares?

Nice! I had good times there

King Cole Cocktail (Savoy) 1 Glass Rye or Canadian Club Whisky. (2 oz Bonded Rittenhouse Rye Whiskey) 2 Dashes Syrup. (1 sugar cube) 1 Dash Fernet Branca. 1 Lump of Ice. Muddle cube and Fernet. Stir well.

Fernet Branca Cocktail (Savoy) 1.5 oz dry gin 0.75 oz Italian vermouth 0.75 oz Fernet Branca Stir and strain!

more progress!

done!

excellent second post!
