I definitely have some ... Some where.

It's more important to use E96 series resistors than the tolerance levels.

Nice! Down to my last few of those Tonite:

I believe the new chargers put out more current, though they look the same. It will work, just take a bit longer.

I like the Mjolnir 1 + HD800 - not sure if it's musical or sterile, it's just "right".

My assembly order arrived! Complete with quality stickers!

... And doing something useful. Any guesses on what?

cross-post, but in case anyone is interested: http://www.diyaudio.com/forums/swap-meet/291234-fs-nelson-pass-vfet2-front-end-pcbs.html#post4712322

prestoclassical.co.uk seems a winner.

At this point, I would say VMWare - as much as it pains me to say.

I am looking for a few OOP classical recordings on SACD (Mercury Living Presence, Vanguard Classics, MFSL, Telarc, Everest, etc.) and was wondering if anyone has go to places other than Amazon, EBay and ImportCD/DeepDiscounts they can recommend checking?

Even scarier

How sensitive is this supply to external capacitance? It seems low-Q capacitors such as film bypass could cause lower performance. Has anyone looked into this?

Apparently HD800 cables are not bunny proof why couldn't the bunny have worked on the power cables not a few feet from the headphones?

I have some, but I am not sure how accessible they are. I am on vacation in FL, when would you need them by?

Once you go connectors, you don't go back

Cool, I would be glad to start the layout. I have a specific width in mind though, and would not have the rectifiers or bulk capacitance on the board, so we might have slightly different use cases. That being said, sure, I would love the models (and any answers you have arrived at)

Has anyone done analysis of the circuit to see if any the semiconductors could be replaced with SMD and what resistor power ratings could be used? I would target 1A output at +/-23VDC output using a 20VAC transformer as input.

KG: can I get a link to the most up to date schematic?

Here is a low pass filter board, utilizing above discrete opamp

I have a real simple question maybe someone can help me with. Given an opamp connected as a buffer, if instead shorting the output and inverting input, I place a resistor here, this should have the effect of bandwidth limiting the buffer effectively, correct? How can I calculate the effect of this value on the overall bandwidth? I can't seem to find this discussed in any detail in intro texts on opamp circuits.

Here is a PTFE trimmer measuring 1pF

Oh yeah, it does much lower. The caps are mislabeled.

Am I doing it wrong? I hope I don't have to start over!

Do you have a supplier for these in the US. It's an easy enough thing to do, so I might as well. McMaster-Carr
