BTW, I just grabbed the link from Amazon, but don't know that they have the best pricing around.

Yeah, the helping hands that you normally buy suck. So does the magnifying lens. I still use my helping hands thingy occasionally, but normally just use my panavise circuit board holder (ebay). I also use an Optivisor: Amazon.com: Donegan OptiVisor Headband Magnifier 2 1/2X Magnification: Industrial & Scientific Mine is the highest magnification, which while fine for looking soldering joints over, etc., puts me too close into the work when soldering so I really should buy another lens for it (you can buy them separately). Good thing I like soldering fumes

Happy Birthday Luis!!

DynaFET on your head... let me know how that works out

Anti-trust? With the previous administration that allowed among other things, AT&T?

From what I've read, in their past life of building power amps, they seemed to be garnering the same sort of reputation as Flame Phase Linear did...

Must be nice not having a home decorating unit (HDU) around to nix working on the living room floor Those umbilicals look like fun...

Iowa kicking GT...

A lot of those guys in the Valab thread seem to like distortion Head-Fi: Covering Headphones, Earphones and Portable Audio - View Single Post - Valab NOS DAC - subjective listening and modifications, and confusing analog mods with digital (silver digital cables. ad nauseum). That and many simple NOS DACs roll off the high end, not unlike some of the tube amps that are or were popular supposedly do, such as the Doge and the Bada (IIRC).

I ordered some feet and cups as well. I knew it was Rick Roberts when I saw the SimplyPhysics link. Are they going out, or is he just liquidating older product? I don't think SimplyPhysics has been real active the last few years, but I could be wrong. I have one of their IsoDrives in one of my CD players and still like it.

Happy Birthday!

You're probably aware that you can get ribbons for these? Not child proof, but replacements nonetheless (at least you could when my brother got replacements for his Centaurs).

Happy Birthday Reks!

Thanks. I did it manually after doing some googling and had forgotten about Doug's scripts . I'll take a look at these when I get home later this week. I settled on 192k for car use and seems OK. It woud be nice not to have to store multiple versions; just lossless then downgrade when putting them on the ipod.

Similar so I just tacked on to this thread. Sorry for being clueless when it comes to itunes and ipods. If I rip CDs using Max as ALACs and get them added to my itunes library, is there anyway that I can copy these over to my ipod but encoded in a lossy format to save space? And recommended format or bitrate? Mostly rock, so 160kbps? higher?

I know the B&K that I have is tracking (i.e., channel B tracks channel A) and they are isolated, so to do a +/- supply you patch the + of channel A to the - of channel B. Channel A is then the - supply and B the +. I don't think it will do 0.5A, don't think it has current limiting, and only does 25V on each (or is that 20?). Something close does exist though. I would look at the HP dual supplies if it were me. This one that I linked previously appears to meet your needs: http://cgi.ebay.com/Hewlett-Packard-HP-6228B-Dual-DC-Power-Supply-w-manual_W0QQitemZ360214245044QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item53de712eb4

Happy unBirthday Ken!

Wouldn't a standard wall outlet work as well?

Was this the addition of a pair of diodes between the VAS stage BJTs, and reduction of the resistor from 510 to 215 ohms? That's the only change I am aware of. This amp has that, but didn't take it as far as was meant by bonding the diodes to the output stage transistors. I could never hear a difference in this mod.

Yeah, they made no attempt to put the singles next to each other, which really would have been pretty easy to do. The PSU in the Gilmore Ref is the original tracking design with the OPA548s, so would be better than what is in this. This appears to be a simple LM317/337 PSU. These guys claim they switched transistors... wonder what they used and if it is an improvement over the Toshiba 2SA1015/2SC1815 used by the original design? Really can't think of many areas to "tweak" one of these designs. Certainly not to the level of "puffery" they allude to. Still, for the price, not bad. Hope the PCB doesn't suck like some "blue" boards I have worked on. Poor copper bonding to the substrate in those.
